A shoe for simulating exercising on natural granular material. The shoe includes a shoe upper, a shoe outsole and a flexible midsole guard element that forms a chamber between the shoe upper and the outsole. The shoe further includes at least one bladder located in the chamber and that is attached to the shoe upper. The bladder includes synthetic granular material having a simulation distribution of synthetic granular material for simulating exercising on natural granular material. The bladder is compressed by the shoe upper during exercise to displace the synthetic granular material wherein the bladder is subsequently expanded by upward movement of the shoe upper during exercise to redistribute the synthetic granular material and again form a simulation distribution of synthetic granular material.

A cap for capping an upper surface of a shoe a first layer, a second layer, and a third layer. The first layer has an outer surface that has a coefficient of friction that is greater than that of the upper surface of the shoe that the cap caps. The second layer is an adhesive layer. The third layer is a release layer that can be peeled off the adhesive layer to expose it, thereby enabling the adhesive layer to stick to the shoe.

A system, method and footwear sensor unit a footwear sensor unit removably attachable to footwear, the footwear sensor unit including: an Inertial Measurement Unit (IMU) including a 3-axis accelerometer and a 3-axis gyroscope, the IMU adapted to gather sensor data of detected movements of the footwear; and a storage device in electronic communication with the IMU, the storage device for storing the sensor data; and a communications module in electronic communication with the storage device, the communication module configured to transmit data to an external computing device.

The present disclosure is directed to an apparatus, system and method for efficiently and rapidly cleaning the bottom of a shoe. The system includes a base having a plurality of alternating, complementary shaped cleansing portions separated by grooves. The configuration of the cleansing portions provides for a sturdy and efficient device for cleaning the bottom of a shoe.

This is a portable, temporary and completely reversible method of adapting a shoe generally used for sports training (with rubberized sole) into a modified shoe (with low coefficient of friction) capable of specialized activity needed for figure skating training (to find and keep axis orientation, primarily, but not limited to: jumps, spins and pivots) on a variety of floor surfaces including carpet, bare floors, floors with mild texture, rubber mats and rubberized floors. This method comprises: providing a piece of material to completely cover the underside front half sole of the shoe (from toe to the mid-arch area of the foot) with the properties for creating greatly reduced friction with the floor surface. The half sole piece is held in place by a configuration of elastic or non elastic material which connects to the device's sole at front and side edges, and slips over the upper portion of the shoe. An additional band of elastic or non-elastic material extends around the back of the shoe to secure the sole piece from back to front much like a sandal overshoe. When attached to the shoe securely, the shoe accessory half-sole piece reduces friction between the floor covering such as carpet or rubberized floors and the shoe for figure skating training exercises.

A stalk sock can provide improved stealth by reducing foot impact noises and the like. The stalk sock can cover a foot, with or without a boot or other shoe, and can include a leg covering and a foot covering portion that extends from the leg covering. The stalk sock can be worn over a pant leg or it can be integrated with a pant leg.

A method of coupling a boot toe body to a fin apparatus is disclosed. The fin apparatus includes a fin body coupled to a boot coupling body. The method involves connecting a first boot connector on a first end of the boot coupling body to a first complementary boot connector on a top side of the boot toe body, and connecting a second boot connector on a second end of the boot coupling body to a second complementary boot connector on a bottom side of the boot toe body. Boot toe bodies, fin apparatuses, and systems including the boot toe bodies and fin apparatuses are also disclosed.
