The soft boot and liner include a moisture transfer system that includes an inner fabric layer carefully selected from technically advanced fabrics. A series of layers are provided outside the inner liner including foam material layers, spacer fabrics and breathable membranes, in various orders. Encapsulation technology and waterproofing are used as well. The outer fabric layer is also capable of working with the other layers to promote the transfer of moisture. Frothed foams and flocking with fibers are further characteristics of the present invention. The moisture transfer system is incorporated into a soft boot or skate or as a removable liner for a shell boot. Numerous other modifications and applications are disclosed.

A skate boot comprising an outer shell with a heel portion for receiving the heel of the foot; an ankle portion for receiving the ankle, the ankle portion comprising a rear portion for facing at least partially the lower part of the Achilles tendon; and medial and lateral side portions for facing the medial and lateral sides of the foot respectively. The skate boot also comprises a tendon guard extending upwardly from the ankle portion of the outer shell for facing at least partially the upper part of the Achilles tendon, the tendon guard comprising a recess for receiving an insert. The tendon guard has a first flexion mode when no insert is received in the recess and a second flexion mode when the insert is received in the recess. The second flexion mode is different from the first flexion mode.

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 footwear warming system and device includes a boot and a footwear warming device. The footwear warming device may include a cap and be generally shaped to fill a void inside the boot. Hot water, or other liquid, may be poured into the footwear warming device to warm a boot.

A disposable, low friction, breathable bootie is provided that accommodates the shape and size of a human foot. The bootie is made from a thin, flexible polymer sheet-like material in a generally tubular form. The bootie has a foot portion, a lower leg portion, and an ankle portion therebetween. The bootie includes a series of air vents in the foot portion and lower leg portion to provide airflow to the foot, while such vents are located to avoid key friction points between the foot and the ski boot during the donning and doffing processes. The bootie facilitates donning and doffing a ski boot. The vents provide breathability while the bootie is worn within the ski boot.

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 sock and/or outer footwear having one or more portions with reduced frictional characteristics. One or more of the heel portion, the arch portion and the ball portion of the sock and/or interior of the outer footwear is fabricated with one or more fibers having the reduced frictional characteristics. The reduced frictional characteristics are established with the one or more low-friction fibers that are integrated with fibers having additional complementary characteristics of thermal regulation and moisture management. The provision of reduced frictional characteristics in one or more of the heel, arch and ball facilitates insertion of a foot into footwear.

Ski boot with rigid shell comprising a lower shell (30) and a cuff (20) articulated in rotation to the lower shell (30), characterized in that it comprises at least a connecting ring (10) connecting the cuff (20) to the lower shell (30), this connecting ring (10) comprising a locking surface (11) collaborating with an opening (31) in the lower shell (30) so as to prevent the connecting ring (10) from rotating relative to the lower shell (30), and a rotation surface (12) collaborating with an opening (24) in the cuff so as to guide the rotation of the cuff (20) relative to the lower shell (30) about this second surface.
