A force absorbing device for a footwear appliance includes a shoe sole having a planar sole surface, such that the shoe sole is adapted to be disposed against a ground surface such as turf, grass or dirt. A ground interface member having a general appearance of a footwear cleat extends from the planar sole surface. Within the sole, the ground interface member couples to a force mitigation assembly for absorbing forces against the cleat. The force mitigation assembly includes an elastic field of a resilient, compressible material, and an inclined surface is disposed against the elastic field and oriented to compress the elastic field. A linkage or connecting surface transmits a displacement force for disposing the inclined surface across the elastic field, where the inclined surface compresses the elastic field as it moves across. In response, the elastic field exerts a counterforce against the ground interface member.

An anti-slip unit included in soles of shoes to provide an anti-slip function for the shoes includes a main body including an inner space and a spike through-hole connecting the inner space and the outside, a spike provided in the inner space so as to be movable along the spike through-hole, and a movable member that is provided in the inner space so as to be movable and that moves to allow the spike to be moved. The movable member moves between a first position in which at least part of the spike is concealed in the inner space and a second position in which the spike is exposed outside the main body and an exposed state of the spike is maintained. The spike may be concealed in, or exposed outside, the above-configured anti-slip unit of the present disclosure, and a user may simply and conveniently manipulate the anti-slip unit.

An article of footwear may include a sole structure fixedly attached to an upper defining an internal cavity configured to receive a foot of a wearer. The sole structure may include an exposed outer member configured to contact the ground, the exposed outer member including a first aperture, and a sensory feedback member disposed at least partially within the first aperture in the outer member, the sensory feedback member including a first end and a second end. The first end of the sensory feedback member may include a projection extending through the first aperture and configured to contact the ground. In addition, the second end of the sensory feedback member may include a plurality of flexible bristles extending through a portion of the sole structure and exposed to the internal cavity.

Disclosed herein are systems and methods for transforming footwear. A footwear system includes one or more portions configured in a first profile. The footwear system includes one or more sensors configured to generate a value based on a surface in contact with at least one of the one or more portions. The footwear system includes an actuator configured to change, responsive to determining that the value satisfies a profile configuration condition, a configuration of the one or more portions from the first profile to a second profile in accordance with the surface.

A shoe with spikes is disclosed. The shoe includes an accommodation seat, at least one moving plate, a transmission module, a plurality of posts, a plurality of spikes, and a shoe plate. The accommodation seat includes a chamber. The moving plate is disposed in the chamber and controlled to move between a first position and a second position, and includes a plurality of push members. The transmission module is configured to move the moving plate. The posts extend from the accommodation seat toward the ground. The spikes are fixed to the posts and extend out of the chamber. When the moving plate is in the first position, the spikes protrude out of the shoe plate relative to the ground. When the moving plate is moved to the second position, the push members push the shoe plate, and the spikes do not protrude out of the shoe plate.
