Technical Field

[0001] This utility model relates to the field of footwear, and in particular to a removable shoe cover insole for shoe cavity. Background Technology

[0002] In the footwear-related service industry and personal hygiene protection field, such as shoe retail try-on, shared shoe rental in gyms and yoga studios, bowling alleys, ice rinks, rehabilitation centers, and medical orthopedic shoe trials, how to avoid foot hygiene problems (such as fungal transmission, cross-contamination of odors, and sweat contamination) caused by multiple people sharing the same pair of shoes is a long-standing pain point. Most solutions on the market use shoe covers on the outside of the shoe to prevent cross-contamination, but this is not feasible in these specific locations. Therefore, there is a need to design a disposable or reusable hygienic insole that can be placed directly inside the shoe. Shoe cover insoles can reduce the difficulty and labor intensity of cleaning. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a breathable, easy-to-use, and customizable detachable shoe cover insole for shoe cavity.

[0004] This utility model is achieved by the following technical solution: a detachable shoe cover insole for shoe cavity, including a shoe cover insole body, the shoe cover insole body is made of environmentally friendly fiber paper, the shoe cover insole body includes a surface layer and a connecting part, the lower end surface of the surface layer is provided with a connecting layer, the connecting part is provided at the outer edge of the surface layer and extends towards the insole or midsole, the shoe cover insole is fitted onto the insole or midsole, the connecting part is detachably fitted onto the side and / or bottom surface of the midsole or insole, and the connecting layer is attached to the upper end surface of the midsole or insole.

[0005] Furthermore, the connecting part is provided around the outer edge of the surface layer to form a perimeter connecting part, and the connecting part is fitted onto the shoe midsole or insole, with a tapered edge at the lower opening end of the connecting part.

[0006] Furthermore, the connecting part includes multiple connecting straps, which are symmetrically arranged in pairs at the outer edge of the surface layer. A textured surface is provided on one side of the outer end of each connecting strap. A hook-and-loop fastener adapted to the textured surface is provided on the bottom of the shoe midsole or insole. The surface layer covers the upper surface of the shoe midsole or insole, and the textured surface of the connecting strap is attached to the hook-and-loop fastener.

[0007] Furthermore, the connecting layer is a textured surface layer, and the upper surface of the shoe midsole or insole is provided with a hook-and-loop surface layer adapted to the textured surface layer, and the textured surface layer and the hook-and-loop surface layer are bonded together with Velcro.

[0008] Furthermore, the connecting layer includes a forefoot connecting layer and a heel connecting layer. Both the forefoot connecting layer and the heel connecting layer include multiple silicone strips. Each silicone strip has multiple micro-suction cups on its end face facing the midsole or insole. When the shoe cover insole body is in the fitted state, the connecting layer on the lower end face of the surface layer adheres to the surface of the midsole or insole.

Other parts of the surface layer are fixedly connected to the padding layer. An arch support pad can be placed inside the arch support pocket, and heel pads can be placed inside the left heel support pocket and the right heel rubbing pocket.

[0013] The beneficial effects of this utility model are: 1. The shoe cover insole is removable, allowing for direct replacement or cleaning, saving time and effort. It is especially suitable for public places where shoes need to be changed, greatly reducing labor costs. 2. The shoe cover insole is made of environmentally friendly fiber paper. The porous structure and moisture-absorbing properties of the environmentally friendly paper layer accelerate the evaporation of sweat, and the natural antibacterial ingredients inhibit the growth of bacteria and reduce shoe odor (after testing, the shoe cavity humidity is ≤55% and the bacterial colony count is ≤100 CFU / cm² after 4 weeks of use). 3. The surface layer of the shoe cover insole can be customized with the appropriate curvature to meet the specific needs of the insole or midsole, ensuring a precise fit between the insole and the midsole or outsole. Combined with the micro-protrusion structure on the surface, it reduces foot slippage and localized pressure, making it especially suitable for wide feet, flat feet, and other special foot types. The environmentally friendly fiber paper uses biodegradable materials (such as bagasse pulp paper), which can naturally degrade after disposal (degradation period ≤180 days), reducing white pollution.

Detailed Implementation

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Reference Figures 1-4 The first embodiment of this utility model provides a detachable shoe cover insole for shoe cavity, including a shoe cover insole body 1. The shoe cover insole body is made of environmentally friendly fiber paper, which is plant fiber paper or biodegradable synthetic fiber paper. The thickness of the environmentally friendly fiber paper is 0.3-1.0mm (preferably 0.5mm), balancing lightness and durability. The plant fiber paper includes sugarcane bagasse pulp paper or bamboo pulp paper, and the biodegradable synthetic fiber paper includes PLA polylactic acid fiber paper. The fiber paper forms a porous structure, accelerating air circulation within the shoe cavity (breathability ≥3000g / (m²·24h)) while absorbing foot sweat (absorption ≥5g / m²). The upper surface of the surface layer is covered with an antibacterial layer, the components of which include chitosan antibacterial agent and / or Artemisia argyi extract, inhibiting common foot bacteria such as Staphylococcus aureus and Candida albicans (antibacterial rate ≥90%).

[0018] The shoe cover insole body 1 includes a surface layer 2 and a connecting part 3. The connecting part 3 is located at the outer edge of the surface layer 2 and extends towards the insole or midsole 4. The shoe cover insole 1 is fitted onto the insole or midsole 4. The connecting part 3 is detachably fitted onto the side and / or bottom of the midsole 4 or insole. The lower end of the surface layer 2 has a connecting layer 5, which is attached to the upper end of the midsole 4 or insole. The surface layer 2 can be customized according to the curvature of the inner end of the specific insole or midsole to achieve a precise fit between the shoe cover insole body and the midsole or insole. The shoe cover insole body 1 is detachably connected to the midsole 4 or insole, and then the midsole or insole is placed back into the shoe body 8, facilitating regular replacement of the shoe cover insole body and maintaining shoe cavity cleanliness. The connecting layer 5 is attached to the upper end of the midsole or insole, ensuring a tight connection between the surface layer 2 and the midsole or insole, preventing the shoe cover insole from slipping during walking and improving wearing comfort. Meanwhile, the surface layer can be printed with patterns to meet users' customization needs. When the shoe cover insole is used as the midsole, the midsole is removable, such as in clogs or slipper-style sandals.

[0019] Specifically, the connecting part has two structures, as follows: 1) The connecting part 3 is arranged around the outer edge of the surface layer 2 to form a perimeter connecting part. The connecting part 3 is fitted onto the midsole or insole of the shoe, and the lower opening edge of the connecting part 3 has a closed end. When the shoe cover insole body is fitted onto the midsole or insole of the shoe, the closed end of the connecting part is placed at the bottom of the midsole or insole. 2) The connecting part 3 includes multiple connecting straps, which are symmetrically arranged in pairs at the outer edge of the surface layer. A textured surface is provided on one side of the outer end of the connecting strap, and a hook-and-loop fastener adapted to the textured surface is provided at the bottom of the midsole or insole. When the surface layer covers and adheres to the upper surface of the midsole or insole, the textured surface of the connecting strap adheres to the hook-and-loop fastener. (The textured surface and hook-and-loop fastener are the mother-daughter fasteners of Velcro, which is existing technology and is therefore not shown in the accompanying drawings.) The connecting layer 5 consists of multiple textured surface layers. The upper surface of the shoe midsole or insole is provided with multiple hook-and-loop fastener layers 6 adapted to the textured surface layers. These hook-and-loop fastener layers 6 are arranged in an array on the upper surface of the shoe midsole or insole (spaced 2-5mm apart), covering 80%-90% of the area of ​​the midsole substrate or insole upper (leaving a 1-2mm unfastened area at the edge to avoid interference with the shoe upper). When the insole cover is fitted onto the shoe midsole or insole, the textured surface layer 5 and the hook-and-loop fastener layers 6 are Velcro-adhesively bonded. This reversible adhesion between the hook and loop fasteners prevents the surface layers from shifting, ensuring a tighter connection between the surface layers and the shoe midsole or insole, improving wearing comfort, and facilitating disassembly. The peel strength between the hook-and-loop fastener layers and the textured surface layers is controlled at 0.5-1.5 N / cm, ensuring they do not fall off during daily wear while also facilitating manual disassembly.

[0020] The upper surface of the surface layer has several micro-protrusions 7, each with a diameter of 0.1-0.2 mm and a height of 0.05-0.1 mm, to increase friction with the foot and prevent slipping.

[0021] Reference Figure 5 The second embodiment of this utility model provides a detachable shoe cover insole for shoe cavity, which is basically the same as the first embodiment, except that: the connecting layer 5 includes a forefoot connecting layer 51 and a heel connecting layer 52. Both the forefoot connecting layer 51 and the heel connecting layer include multiple silicone strips, and each silicone strip has multiple micro-suction cups 53 on its end face facing the midsole. When the shoe cover insole body is in the fitted state, the connecting layer on the lower end face of the surface layer adheres to the midsole or insole surface. The forefoot and heel silicone strips are arranged in an arc shape according to the curvature of the midsole or insole. This embodiment is preferably suitable for clogs with detachable midsoles, where the micro-suction cups adhere to the detachable midsole, achieving a close fit between the shoe cover insole and the midsole. When worn, the silicone strips protrude towards the foot, enhancing the anti-slip effect and effectively preventing the foot from sliding back and forth or swaying left and right inside the shoe, which is especially important for sudden stops or changes of direction. Simultaneously, it improves cushioning and impact protection. (See reference...) Figures 6-7 The third embodiment of this utility model provides a detachable shoe cover insole for a shoe cavity, which is basically the same as the first and second embodiments, except that: the surface layer 2 includes a contact layer 21 and a padding layer 22, with the padding layer 22 located below the contact layer, and a connecting layer located on the lower end face of the padding layer (facing the insole or midsole). An arch support pocket 23 is formed between the padding layer 22 and the contact layer 21 at the arch, and a left heel support pocket 24 and a right heel padding pocket 25 are formed at the heel. The remaining parts of the surface layer are fixedly connected to the padding layer. An arch support pad can be placed inside the arch support pocket 23, and heel pads can be placed inside the left heel support pocket 24 and the right heel padding pocket 25. Users can insert an arch support pad or a heel pad at the arch, left side, or right side of the heel, depending on their foot condition. For example, people with flat feet can place arch supports in their arch pockets to provide sufficient support for their arches. Different materials and heights of arch supports can be chosen according to individual needs. People with X- or O-shaped legs can insert heel pads on the left or right side of their heels to achieve a corrective effect, depending on their individual needs. There's no need to customize professional corrective shoes; the corrective effect is achieved by inserting arch supports or heel pads, making it a relatively low-cost solution.
