A system for analysis of user gait and to provide correction in form of haptic and visual feedback. This system comprises a motion and force sensors and a haptic actuator embedded in the user shoe insoles in communication with a smart-phone based analysis application, configured to calculate motion and orientation of the user feet in relation to the value, location and distribution of ground reaction forces measured by sensors located in the shoe insoles and after analysis of said forces and motion, to provide haptic feedback to the user foot instructing about the location (and timing) of pressure the user must apply to achieve an optimal gait.

A system for analysis of user gait and foot disorder intended to minimize risks ulceration and limb amputation associated with the uncontrolled increase of the foot temperature in persons with diabetes. This system comprises a motion, force and temperature sensors and a processing element configured to process motion algorithms, measure ground reaction force (GRF) and changes in foot temperature embedded in the footwear insoles in communication with a smartphone based analysis application using wireless radio interface. The analysis application processes data received from the footwear sensors, compares the results with set of criteria and rules, and if any of the predefined criteria is exceeded, provides alerts to the user and the remote medical supervisor. Additionally, the insoles may be equipped with a haptic actuators configured to determine the level of the user neuropathy by measuring vibration perception threshold (VPT) level.

A skate having a skate boot with a non-lasted boot shell, the shell having a first non-lasted three-dimensional sub-shell and a second non-lasted three-dimensional sub-shell, the second sub-shell being interior to and adjoining the first sub-shell, the first sub-shell comprising a first material having a first density and the second sub-shell comprising a second material having a second density, the second density being less than the first density, the shell being shaped so as to have a heel portion, an ankle portion, a lateral portion, a medial portion, and a sole portion; and a ground-engaging assembly disposed on an underside of the skate. Additional sub-shells are possible. Methods of manufacturing the skate boot shell, including molding and build-up, are also disclosed.

The waterproof/breathable moisture transfer liner for a running and hiking shoe includes an inner liner selected from technically advanced fabrics which are carefully selected. A series of layers are provided outside the inner liner including foam material layers, breathable membranes, a supportive mesh or a moldable foam, and an outer shell fabric. The applicability of the liner to alpine, snowboard boots, cross country, hiking boots, protective gear and helmets, along with appropriate variations for each application.

A wearable article such as an article of athletic gear (e.g., a skate, an article of protective athletic equipment such as a helmet, etc.) wearable by a user and comprising an expandable user-engaging structure that is configured to be expanded (e.g., by heat or another stimulus) after manufacturing of the wearable article to conform it to the user or otherwise improve a fit of the wearable article on the user.

Sports boot comprising: an inner boot (3); an exogenous shell (1), the dimensions of which allow said inner boot (3) to be inserted into or extracted from it, said exogenous shell strengthening said inner boot and allowing it to be attached to a piece of sports equipment; wherein said exogenous shell comprises a sole (10), a forward part of an upper (11) able to pivot with respect to said sole (10) about a first articulation (110), and a rear part of an upper (12) which is able to pivot with respect to said sole (10) about a second articulation (120).

A boot for a roller skate system has a three-point fastening system for fastening the boot to a rail. The three-point fastening system includes three fastening devices, wherein the first fastening device is arranged in a central position in the heel region of the boot, the second fastening device is arranged on an outer side in the ball region of the boot, and the third fastening device is arranged on an inner side in the ball region of the boot. The rail that can be mounted on the boot is also described.

Waterproof articles of footwear having an improved fit and waterproof stretchable liners are provided. The footwear and liners of the present technology may include various stretchable components configured to tightly secure and conform to a user's foot and adapted to provide a tighter and more versatile fit around the differently sized and shaped feet of various different users. In some aspects of the present technology, the waterproof liner may contain one or more stretchable panels and one or more non-stretchable or less stretchable panels. In other aspects, waterproof footwear may be provided with stretchable components such as straps or bands adapted to secure a user's foot.

To provide a sports inner boot that ensures removal from a sports outer boot to allow an inside to be easily washed and where a drying time be a comparatively short time. A sports inner boot made of a thermoplastic plastic includes a bottom plate disposed in the sports outer boot and a foot wrap portion formed at the bottom plate. The bottom plate and the foot wrap portion are integrally formed. The bottom plate and the foot wrap portion contain an ethylene vinyl acetate copolymer material (EVA).
