Technical Field

[0001] This utility model belongs to the field of footwear technology, specifically an adult stability shoe. Background Technology

[0002] Foot problems are often related to footwear. Inappropriate shoes can lead to calluses, bunions, friction injuries, collapsed arches, and big toes wearing through insoles. Existing adult shoes often focus on style and design, with less consideration for the physiological characteristics of the feet of this population. As a result, common problems include excessive stress on the forefoot and heel, leading to fatigue after long walks; unreasonable opening and closing mechanisms in the shoe upper, making them inconvenient to put on and take off, especially for middle-aged and elderly people; and poor stability of the shoe upper, especially the heel, failing to provide stable ankle support. To address these issues, this application proposes a stability shoe for adults. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3 As shown, this utility model provides an adult stability shoe, including a sole and an upper 4. The sole consists of a bottom sole 1, a midsole 2, and an insole 3. The bottom sole 1 has a trapezoidal cross-section and a wide sole design, which widens the internal space of the foot and the force-bearing area of ​​the outsole, making it suitable for people with wide feet, moderate bunions, and collapsed arches. The bottom of the bottom sole 1 has anti-slip protrusions 11 and anti-lateral slip patterns. The anti-slip protrusions 11 cover the entire bottom of the bottom sole 1, making the coefficient of friction of the sole greater than 0.35. It has a certain degree of hardness, and the pattern design can prevent lateral slippage and tilting, effectively ensuring the stability of the user during wear.

[0020] like Figure 2 As shown, the midsole 2 includes an embedded footbed 21, the edge 22 of which protrudes 0.5~1cm from the bottom of the footbed, improving the stability, support and protection of the movement, and achieving a more reasonable effect of the shoe and foot as one; the forefoot area and heel area of ​​the footbed 21 are provided with grooves 23; the bottom of the insole 3 has protrusions in the forefoot area and heel area that cooperate with the grooves 23, so that the insole 3 and the midsole 2 are more firmly fixed, and the insole 3 is prevented from shifting during vigorous exercise.

[0021] The insole 3 features a soft support structure 31 at the arch. This soft support structure 31 is a smooth curved surface that conforms to the physiological curve of the arch, matching the direction of the plantar fascia and muscles. It extends beyond the metatarsal heads at the front and beyond the heel at the back. It can be made of, but is not limited to, a rigid TPU sheet, designed in a wave-like arch shape and integrally molded with the insole 3. This provides strong vertical support while allowing for some horizontal deformation, thus achieving a balance between support and movement. Simultaneously, it smoothly transitions to the supportive heel counter at the back and to the slight protrusion behind the bulbocele at the front. The well-supported heel cup locks the heel in place, preventing lateral movement and providing a stable foundation for arch support. The protrusion behind the bulbocele distributes pressure on the forefoot, enhancing overall comfort.

[0022] like Figure 3 As shown, the inner side and heel edge of the insole 3 are set with a certain upward fold.

[0023] The heel counter of the upper (upper part 4) is approximately 2.5-4cm high from the shoe opening. The inner cavity of the heel counter has a three-dimensional curved structure that conforms to the shape of the human heel. The heel counter of the upper (upper part 4) is made by laminating a layer of slow-rebound foam on the inside of the rigid hot-melt adhesive heel, the side that contacts the foot. The rigid heel provides macroscopic structural support, while the inner foam fills the gap between the foot and the heel, adapting to different foot shapes and providing a sense of comfort. Combined with the cup-shaped insole (insole part 3), it effectively protects the ankle, prevents ankle sprains, and increases stability.

[0024] The soft support structure 31 disperses pressure on the forefoot and sole, creating a more comfortable foot feel.

[0025] Preferably, the toe circumference and instep circumference of the shoe last of this stable shoe are increased by 2-4cm compared to the standard last, so as to avoid foot compression and adapt to the needs of middle-aged or elderly people with swollen or deformed feet.

[0026] Preferably, the heel-toe drop of the sole 1 is 8-10 mm.

[0027] As a preferred design, the last of this stable shoe has a 2-6cm increase in the height of the big toe compared to the standard last. This reduces pressure on the big toe area and accommodates the overlapping toes of moderate hallux valgus / valgus feet.

[0028] Preferably, the upper 4 adopts an openable lacing structure with an opening angle of 43°~47°. It uses inverted triangular eyelets with flat shoelaces, which is more comfortable for different instep heights and can be adjusted according to foot shape, eliminating the pressure on the instep. The sides of the shoe tongue are equipped with pull rings that do not shift, making them easy to put on and take off and more aesthetically pleasing. Combined with the 45° heel of the sole 1, the shoes can be put on without bending over or lifting, making them simple and easy to wear.

[0029] Preferably, the inner side of the shoe upper 4, corresponding to the heel and the tongue, is provided with thickened sponge, which increases the comfort of wearing and the fit between the foot and the shoe.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
