Abstract: The anti-slip structure comprises a body, on which an embedded replaceable shock-absorbing anti-slip device for shock absorption and anti-slip function is detachably arranged. This device comprises an embedded stud assembly, which comprises a guide member movably arranged up and down, a fixed base, and an anti-slip portion arranged between the guide member and the fixed base. The guide member is configured to guide and engage the shock-absorbing anti-slip device, the fixed base is configured to prevent detachment of the shock-absorbing anti-slip device, the anti-slip portion is configured to prevent slipping and grip the ground when contacting with the ground. The embedded stud assembly of the present invention can adapt to ground conditions. When coping with extreme terrains such as wet slippery rocks, muddy mountain trails, or frozen soil, the spring undergoes elastic deformation in response to changes in the center of gravity, absorbing shocks, enhancing comfort, and reducing foot fatigue.

Abstract: A cover for a spiked athletic shoe includes toe and heel portions, and a particular mid-section with one or more selective shapes forming an accordion-like structure providing adjustability for a distance between the toe and heel portions. The mid-section is also configured to provide vertical support to a mid-portion of the shoe at each of the first and second ends of the cover's mid-section, being the same as a level of support provided thereat by the toe portion and the heel portion. To mount the cover, a force is applied causing elastic expansion of the selective shape permitting contact between the bottom of the cover and the sole of the shoe, and releasing the force results in contraction of the mid-section, for engagement and securement of the toe portion and heel portion to the front and rear of the shoe, to thereby retain the cover on the shoe.

Abstract: A heel stabilizer apparatus for a shoe comprises a shell with a base, at least one slot in a sidewall, a rod movably arranged relative to the shell, and a leg movably coupled to the rod. Movement of the shell relative to the rod from a first to second position moves the leg to protrude through the slot. A leg resilient element biases the leg to protrude through the slot. A compression post couples to the shell, with a spring positioned between the leg and compression post. The shell has a shell bore with interior surface, and the leg has an exterior contact surface contacting the shell bore in the first position. A resilient element between rod and shell biases them to the first position. The shell comprises a foot pad, and the leg comprises a leg foot pad.

Abstract: The ergonomic high heeled footwear is intended to provide users with a footwear design that addresses the common issues associated with traditional high heel wear, such as foot pain, forward foot slippage, excessive forefoot loading, metatarsalgia, neuromas, bunions, hammertoes, the risk of chronic injuries, and the risk of chronic injuries. To accomplish this, a unique combination of metatarsals indents, arch outdents, toe indents, and a specially designed heel indentation and heel structure, tailored to the natural contours of the foot, represents a breakthrough in ergonomics are applied to high heel design. Further, a layered insole layer made of different flexibilities having specific shapes and made of specific materials provide a combination of support and comfort that matches a variety of foot shapes and contours. An outer covering around the whole structure provides aesthetic appeal and more comfort.
