Description

Technical Field

[0001] This invention relates to the field of footwear technology, specifically to a comfortable method and approach that prevents high heels from slipping off the foot. Background Technology

[0002] Among human physiological characteristics, foot shape exhibits significant individual differences. Numerous studies have shown that over 90% of people have feet that are not the same length. This widespread physiological phenomenon causes many inconveniences in people's daily lives, especially when it comes to choosing footwear.

[0003] Traditional high-heeled shoe design and production are primarily based on standardized foot sizes, aiming to meet the basic needs of most people. However, this "one-size-fits-all" approach often fails to provide an ideal wearing experience for consumers with varying foot shapes. When purchasing high heels, consumers frequently encounter the following problem: when the left foot fits well, the right foot may experience slippage (the shoe easily slips off during walking) or tightness (the shoe exerts excessive pressure on the foot, causing discomfort or even pain); conversely, when the right foot fits well, the left foot experiences similar problems. This not only affects wearing comfort, but prolonged wear of ill-fitting high heels can also lead to foot diseases such as corns, bunions, and plantar fasciitis, seriously threatening consumers' health.

[0004] To address the issues of high heels slipping off and squeezing the feet, existing technological solutions primarily focus on improving shoe lasts and insole design. Some manufacturers attempt to improve shoe fit by optimizing the shape of the shoe last, but this method often only alleviates the problem to a certain extent and cannot fundamentally solve the problems of slipping off and squeezing caused by differences in left and right foot length and foot width. Additionally, some adjustable insoles have emerged, typically adjusting their length through simple sliding or folding. However, these insoles often lack effective locking mechanisms, making them prone to shifting during walking and unable to function stably.

[0005] Regarding shoe heel design, while some measures have been taken to increase stability, such as using specially shaped heel linings or increasing the height and width of the heel, most of these designs do not take into account the elasticity changes and adaptive needs of the heel. For ankles and heels of different thicknesses and contours, traditional heel designs cannot provide sufficient fit and support, and it is still difficult to completely prevent the problem of shoes slipping off.

[0006] Regarding adjustments to the shoe upper, the most common methods currently used are adjusting the tightness of the laces or the elastic material at the shoe opening. However, for high heels, the design of the laces can affect the overall aesthetics and ease of wear, and simply adjusting the elastic material at the shoe opening often cannot meet the precise adjustment needs of different foot widths, especially when a large adjustment range is required; in these cases, the traditional methods are not ideal.

[0007] Furthermore, regarding forefoot comfort, while some high heels use soft insole materials to reduce pressure on the forefoot, they still lack effective cushioning and dispersion mechanisms for the impact of the ground on the forefoot during walking. Wearing such high heels for extended periods can easily lead to fatigue and pain in the forefoot, affecting comfort and overall experience.

[0008] In conclusion, existing high-heeled shoe products still have many shortcomings in addressing issues such as slipping, squeezing, and comfort caused by differences in foot shape. Therefore, developing a new high-heeled shoe design and adjustment method that fully considers differences in human foot shape, effectively solves the problem of high heels slipping off, and significantly improves wearing comfort is of significant practical importance. Summary of the Invention

[0009] The purpose of this invention is to provide a comfortable method and means to prevent high heels from slipping off the foot, and to solve the problems of high heels slipping off the foot and not fitting properly caused by the difference in length between the left and right feet and the poor fit of existing high heels. By adjusting the length of the sliding insole, optimizing the wrapping by the elastic heel cup and the lateral adjustment strap, and combining the design of the cushioned forefoot pad, it can achieve multi-dimensional adaptation to different foot shapes, improve wearing stability and comfort, and reduce discomfort and the risk of slipping while walking.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a comfortable method and means of preventing high heels from slipping off the foot, comprising a high heel body, wherein the upper surface of the sole of the high heel body is provided with an insole assembly that can linearly displace along the length of the shoe, a positioning and locking mechanism with mechanical engagement function is integrated near the front end of the sole of the high heel body, a wrap-around protective ring with deformation recovery capability is provided in the inner area of ​​the heel of the high heel body, retractable and adjustable straps are provided on the inner walls of the left and right sides of the high heel body, the front part of the movable insole is thickened with a soft contact layer for cushioning impact, an elastic support plate for shock absorption is laid in the bottom area of ​​the forefoot of the high heel body, and a layer of skin-friendly and soft padding material is attached to the edge of the heel opening of the high heel body.

[0011] Furthermore, the method involves first placing a sliding insole on the upper part of the sole of the high heel, allowing the wearer to precisely adjust the effective internal length of the shoe by sliding the insole back and forth according to the length difference between their left and right feet. Through the length adjustment function of the sliding insole, this method directly solves the common problem of inconsistent left and right foot lengths, allowing the wearer to personalize the internal space of each shoe, avoiding foot compression or shoe loosening caused by length mismatch, thereby improving walking stability and comfort.

[0012] Furthermore, after adjusting the length by sliding the sliding insole, the toothed locking button located at the inner end of the sole of the high heel can be operated to firmly lock the sliding insole in the adjusted position by pressing or rotating it, preventing it from shifting during walking. The toothed locking button provides a simple and reliable locking mechanism to ensure that the sliding insole remains fixed after adjustment, avoiding length changes or instability caused by insole slippage, thereby maintaining the adjustment effect and enhancing walking safety.

[0013] Furthermore, an elastic heel cup located at the inner end of the heel of the high heel shoe wraps around the heel. The elasticity of the heel cup can adapt to the contours of ankles and heels of different thicknesses to increase fit and stability. The elastic heel cup automatically adapts to the shape of the heel through its elastic material, providing a tight wrap, reducing the gap between the heel and the shoe, effectively preventing the heel from slipping out when walking, and improving overall stability and comfort.

[0014] Furthermore, by pulling the lateral adjustment straps located on the inner ends of both sides of the high heel, the tightness of the upper can be adjusted on both sides, thereby binding the instep and arch from both sides to accommodate different foot widths. The lateral adjustment straps allow the wearer to flexibly adjust the tightness of the upper according to the width of the foot, ensuring that the instep and arch receive even support, avoiding discomfort caused by being too tight or too loose, and enhancing the fit and adaptability.

[0015] Furthermore, a cushioned forefoot pad is placed at the top front of the sliding insole, positioned below the forefoot, to distribute and cushion the pressure of the ground on the forefoot during walking, thus improving comfort. The cushioned forefoot pad reduces local fatigue and pain by absorbing and dispersing the pressure on the forefoot during walking, making it especially suitable for wearing high heels for extended periods, significantly improving comfort.

[0016] Furthermore, the adjustment sequence of this method is as follows: first, measure the length of both feet separately and determine the difference; then, operate the high heel on the shorter foot by sliding its sliding insole to compensate for the length difference; then, adjust the locking and other parts. Through this systematic adjustment sequence, this method ensures that length adjustment is prioritized and accurate. Subsequent steps such as locking and lateral adjustment are based on the length adjustment, thereby optimizing the overall fit and improving adjustment efficiency and comfort.

[0017] Furthermore, the operation of the rack and pinion locking button specifically includes unlocking the insole when adjustment is needed, allowing the sliding insole to slide freely; after adjustment, the rack and pinion locking button is operated again to lock it into the locked state, fixing the position of the insole. The unlocking and locking operation of the rack and pinion locking button is simple and intuitive, allowing the wearer to easily make multiple fine adjustments and ensuring that the insole remains stable while walking, increasing the convenience and reliability of use.

[0018] Furthermore, when placing the sponge pad at the upper heel of the high heel, it is necessary to ensure that the pad fits completely against the inner lining of the shoe upper, without any wrinkles or accumulation, and with a natural edge transition, so as to achieve a close and seamless fit with the skin on the back of the heel.

[0019] Furthermore, the elastic pad should be made of a polymer material with a good coefficient of recovery of compression deformation, and its geometric thickness parameters should be set according to the force distribution data of the foot, so as to ensure that it can fully attenuate the vibration transmission under high load and maintain the integrity of the sole structure without deformation.

[0020] This invention provides a comfortable method and means to prevent high heels from slipping off the foot, and has the following beneficial effects: 1. This design directly addresses the core pain point of inconsistent foot lengths by combining a sliding insole with a toothed locking mechanism. Traditional high heels, due to their fixed insole, often result in the shorter foot feeling cramped due to insufficient space, while the longer foot slips off due to excessive clearance, affecting walking stability. This solution allows users to first measure the difference in foot length and then appropriately move the sliding insole towards the longer foot. This physical compensation eliminates the length difference, ensuring both feet receive a snug and supportive fit within the shoe. For example, if the left foot is 0.5cm longer than the right, the left insole can be moved back 0.5cm, ensuring both feet have equal contact with the sole. This avoids localized pressure or slippage caused by length mismatch, significantly improving the even distribution of pressure on both feet and reducing foot fatigue or pain caused by asymmetrical pressure.

[0021] Through the synergistic action of the elastic heel cup, lateral adjustment straps, and sliding insole, this design achieves a three-dimensional dynamic fit to the foot shape. The elastic material of the heel cup automatically contracts or expands according to the ankle circumference, solving the problem of the heel being loose or constricting due to different ankle sizes. The lateral adjustment straps, by tightening or loosening, flexibly adjust the support of the shoe's sides for the arch and instep, accommodating differences such as wide feet, narrow feet, or high arches. This multi-directional adjustment mechanism of "front-back + left-right + up-down" breaks through the limitations of traditional high heels that rely solely on fixed sizes or simple elastic bands. It is especially suitable for scenarios where feet are prone to swelling, feet swell during pregnancy, or foot shape changes before and after exercise, ensuring a close fit in different situations and reducing the risk of slipping off.

[0022] A cushioned forefoot pad is placed at the front of the sliding insole, combined with an elastic pad at the bottom of the forefoot, forming a full-area pressure distribution system covering the forefoot, midfoot, and heel. The forefoot of high heels is a major stress point, and traditional designs, lacking targeted cushioning, easily lead to forefoot compression pain or fatigue. In this solution, the cushioned forefoot pad directly supports the forefoot using soft materials (such as memory foam), dispersing the ground reaction force; the elastic pad absorbs the impact vibration during walking using its resilience, while maintaining support in the forefoot area and preventing excessive deformation of the sole. Together, these two components alleviate forefoot pressure while maintaining the stability of the shoe structure, making the forefoot less prone to soreness from continuous pressure during prolonged standing or walking, significantly improving the wearing experience.

[0023] The sponge pad design at the heel opening provides a direct solution to the most common problem with high heels: "heel rubbing." Traditional high heels often have hard leather or stiff linings at the heel opening, which can easily lead to redness, blisters, and even skin abrasions due to repeated friction with the skin. This solution adds a soft sponge pad to the inside of the heel opening. Its skin-friendly material reduces mechanical irritation to the skin, while closely conforming to the curve of the heel, filling the gap between the heel and the shoe upper, and preventing direct contact between the skin and hard objects. This design not only reduces the probability of rubbing but also helps stabilize the heel by increasing friction, reducing secondary friction caused by heel slippage. It is especially suitable for the break-in period of new shoes or for people with sensitive skin, protecting foot health.

[0024] The rack and pinion locking mechanism strikes a balance between adjustability and stability. Its tool-free press / rotate operation allows users to adjust the insole position as needed, and lock it in place with a simple operation after adjustment, avoiding the problems of decreased adhesion or breakage caused by repeated use of traditional Velcro or clips. Simultaneously, the sliding insole's track structure, in conjunction with the rack and pinion locking mechanism, ensures stable positioning after adjustment, preventing shifting due to vibration or foot movement during walking, maintaining a comfortable fit for long-term use. This design satisfies users' need for "adjustable" functionality while ensuring effectiveness through a reliable fixing mechanism, extending the lifespan of high heels and reducing the economic cost of frequent shoe replacements.

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] How to use: First, the user should measure the actual length of both feet to determine the difference in length between the left and right feet. Then, proceed with the procedure for the high heels corresponding to the shorter foot.

[0030] First, take out the main body 1 of the high heel and place it on a flat surface. Next, take out the sliding insole 2 and place it stably on the upper part of the sole of the main body 1. At this time, the user can slide the sliding insole 2 back and forth according to the previously measured difference in the length of both feet and their own actual wearing experience. Through this sliding action, the effective length inside the shoe can be precisely adjusted to adapt to the foot size and prevent the shoes from slipping off due to improper length.

[0031] The second step, after adjusting the length of the sliding insole 2, is to secure it. Locate the toothed locking button 3 located at the inner end of the sole of the high-heeled shoe body 1. If the toothed locking button 3 is currently locked, preventing the sliding insole 2 from moving, it must first be released by pressing or rotating it. After the sliding insole 2 is adjusted to the appropriate position, operate the toothed locking button 3 again, pressing or rotating it to firmly lock it in the current position, preventing the sliding insole 2 from shifting during subsequent walking and ensuring the effectiveness of the length adjustment (claims 3 and 8).

[0032] The third step is to adjust the elastic heel cup 4 at the inner end of the heel of the high heel body 1. Place the heel into the shoe, and use the elastic stretching properties of the elastic heel cup 4 to adapt to the contours of ankles and heels of different thicknesses, tightly wrapping the heel, thereby increasing the fit and stability between the heel and the shoe upper, and further preventing the foot from slipping off.

[0033] Fourth, adjust the lateral adjustment straps 5 on the inner ends of both sides of the main body 1 of the high heel. Depending on the width of your foot and your personal comfort needs, pull the lateral adjustment straps 5 appropriately to adjust the tightness of both sides of the shoe upper. This adjustment effectively binds the instep and arch area from both sides, better adapting to different foot widths and preventing the shoes from slipping off due to being too loose.

[0034] Fifth, check that the cushioning forefoot pad 6 at the top front of the sliding insole 2 is in the correct position. The cushioning forefoot pad 6 should be located under the forefoot, and its function is to effectively distribute and cushion the pressure of the ground on the forefoot when walking, thereby improving wearing comfort.

[0035] Step 6: Confirm that the sponge pad 8 is correctly installed at the heel opening of the high heel body 1. The sponge pad 8 should be installed flat and closely fit the back of the heel to provide extra softness and reduce friction between the heel and the shoe upper.

[0036] Finally, check whether an elastic pad 7 is provided at the lower forefoot of the high heel body 1. This elastic pad 7 should be made of a material with moderate elastic recovery properties, and its thickness should be set according to ergonomic principles. Its main function is to effectively absorb shock when bearing walking pressure and maintain the structural stability of the shoe body, further improving the overall wearing experience.

[0037] Example: Example 1: Standard Length Adjustment and Foundation Fixation This embodiment is suitable for users whose left and right feet have slight differences in length but whose foot shape is relatively standard. First, the user needs to measure the length of both feet using conventional methods to determine the shorter foot. For the high-heeled shoe body 1 worn by this foot, the following operations are performed: Take out the sliding insole 2 and place it stably in the preset guide rail or groove at the upper end of the sole of the high-heeled shoe body 1. The user tries on the shoes barefoot or wearing thin socks. When the toe box feels slightly too large, slide the sliding insole 2 towards the rear until the front of the foot and the toe box reach the ideal reserved space, while the toes can naturally spread out. This step aims to precisely adjust the effective accommodate length inside the shoe to compensate for the discomfort caused by the difference in foot length. After completing the length adjustment, the user will notice that there is a toothed locking button 3 at the inner end of the sole of the high-heeled shoe body 1. At this time, operate the toothed locking button 3, by pressing or rotating it to lock it into the locked state, firmly fixing the sliding insole 2 in the current position and preventing the insole from moving back and forth when walking. Next, place your heel against the inner heel of the high-heeled shoe body 1. Utilizing the elasticity of the heel cup 4, it will automatically and tightly wrap around your heel, providing initial stability. Then, check the inner sides of the high-heeled shoe body 1. If necessary, gently pull the lateral adjustment straps 5 to adjust the tightness of the upper, ensuring no pressure on the instep. Finally, confirm that the cushioned forefoot pad 6 at the front of the sliding insole 2 is in place, and that the sponge pad 8 at the top of the heel is installed smoothly. Completing these steps will give you a pair of comfortable high heels that fit well and are less likely to slip off.

[0038] Example 2: Comprehensive adjustment for wider feet This embodiment is designed for users with wider feet, especially those with high insteps or wide arches. First, measure the length of both feet to determine if the foot is shorter. Take out the high-heeled shoe body 1 and the sliding insole 2, and roughly place the sliding insole 2 on the sole. When the user tries them on, they may find that even if the length is correct, there is still a feeling of pressure on both sides of the instep. At this point, focus on operating the lateral adjustment straps 5 on the inner ends of both sides of the high-heeled shoe body 1. By pulling the lateral adjustment straps 5 outwards or inwards, observe the changes on both sides of the shoe upper until the shoe upper can loosely accommodate the instep while maintaining a certain degree of restraint to prevent the foot from slipping off. After the lateral adjustment is completed, fine-tune the front and back position of the sliding insole 2 to ensure free movement of the toes. After adjustment, be sure to operate the toothed locking button 3 on the inner end of the sole to lock the sliding insole 2 to prevent displacement of the insole due to lateral adjustment. Then, use the elastic heel cup 4 on the inner end of the heel to wrap around the heel and feel its elastic support. Finally, it was confirmed that the elastic pad 7 at the lower end of the forefoot provided sufficient cushioning, and the sponge pad 8 at the upper edge of the heel conformed to the heel. Through this series of adjustments, the problem of squeezing the feet caused by wide feet was solved, while ensuring the stability of the footwear.

[0039] Example 3: Depth Adaptation for Longer Legs This embodiment is suitable for users whose one foot is significantly longer than the other. First, accurately measure the length of both feet to identify the longer foot. For the high heel body 1 corresponding to this foot, remove the sliding insole 2. Due to the longer foot, the initial space inside the shoe may be insufficient. The user needs to slide the sliding insole 2 as far towards the toe as possible until the front of the insole is close to the toe cap, while ensuring that the heel can still fit smoothly into the elastic heel cup 4 at the inner end of the heel. During this process, the position of the sliding insole 2 may need to be repeatedly fine-tuned to find the optimal balance point. After adjustment, immediately operate the toothed locking button 3 at the inner end of the sole to lock it and prevent the insole from slipping back. Next, carefully feel the degree of wrapping of the elastic heel cup 4 around the heel, ensuring that it can fix the heel without losing elasticity due to overstretching. Afterward, check the tightness of the lateral adjustment strap 5 to ensure that there is no additional pressure on the sides of the foot caused by the insole moving forward. Finally, experience the shock absorption effect of the cushioning forefoot pad 6 when the forefoot lands, and the soft touch of the sponge pad 8 at the upper edge of the heel. By following these steps, even those with longer feet can achieve a comfortable wearing experience by extending the effective length inside the shoe.

[0040] Example 4: Fine-tuning and locking during dynamic use This embodiment simulates a scenario where a user experiences discomfort while wearing the shoes and makes dynamic adjustments. After walking for a period of time in the high heels 1 that have been adjusted as described above, the user feels a slight slippage in their left foot or excessive pressure on the forefoot. At this point, the user first removes the shoes and locates the toothed locking button 3 on the inner end of the sole. Since it was previously locked, the user needs to release the lock by pressing or rotating it, allowing the sliding insole 2 to slide freely again. To address the slippage issue, the user tries gently sliding the sliding insole 2 of the left foot a short distance backward to increase the heel support; or, if the forefoot feels cramped, slide it forward. After adjustment, walk again until comfortable. Once it's confirmed that no further adjustment is needed, operate the toothed locking button 3 to relock it, fixing the sliding insole 2 in its new position. Simultaneously, check if the elastic heel cup 4 has lost its elasticity due to prolonged wear; if necessary, slightly adjust the foot position to restore its original position. Additionally, check if the lateral adjustment strap 5 still maintains appropriate tension. Through this dynamic fine-tuning and locking mechanism, users can optimize their footwear at any time based on real-time feedback, always maintaining the best wearing condition.

[0041] Example 5: Overall Comfort and Stability Optimization This embodiment aims to comprehensively check and optimize all comfort and anti-slip-off components. The user first follows the standard procedure to adjust the length of the sliding insole 2 and lock the rack and pinion locking button 3. Next, pay special attention to the elastic heel cup 4 at the inner end of the heel, ensuring it is fully extended and fits snugly against the heel without wrinkles or gaps to provide maximum stability. Then, carefully adjust the lateral adjustment straps 5 on both inner ends to distribute force evenly on both sides of the upper, ensuring neither constriction nor looseness. Afterward, turn attention to the lower forefoot area, confirming the presence of the elastic pad 7 and feeling its absorption of forefoot impact during walking. Simultaneously, check if the cushioning forefoot pad 6 at the front of the sliding insole 2 is flat and has not shifted. Finally, check if the sponge pad 8 at the upper heel opening is installed flat and fits snugly against the back of the heel to avoid chafing. Throughout the process, the user can adjust the firmness of the elastic heel cup 4 and elastic pad 7 according to their personal preference for elasticity. Through such comprehensive inspection and meticulous adjustments, we ensure that all components of the high heel body 1 work together to provide users with a comprehensive comfort experience and reliable protection against slipping.
