Described is an insole including: a first body having an upper surface, having a first channel, extending close to an edge of said upper surface, and a second channel, extending between a central zone and an edge of said upper surface; a second body, in contact with the upper surface of the first body for closing said first and second channels, including at least a first through opening, positioned at the first channel, and at least a second through opening, positioned at the second channel; an attachment, constrained to said first and second body, including at least a first conduit, in fluid communication with the first channel and with the outside environment, and at least a second conduits, in fluid communication with the second channel and with the outside environment.

The invention relates to a system for analyzing (1) the use of footwear items (11) configured to determine an association index between use parameter values (101) and shoe parameter values (201), said system a calculation computing device (30) configured for: Obtaining or loading posture or mobility parameter values (301) calculated from raw data generated by at least one connected sole (10); Obtaining or loading geographic parameter values (401) corresponding to a location of the at least one connected sole (10); Obtaining or loading shoe parameter values (201) including values of structural parameters, geometric parameters and/or aesthetic parameters of the footwear item (11); Calculating one or more use parameter values (101); Determining an association index value between the use parameter value(s) (101) and the shoe parameter values (201).

Systems and apparatus related to footwear including a modular lacing engine are discussed. In an example, a modular footwear apparatus including an upper portion, a lower portion, and a lacing engine is described. The upper portion can include a lace to adjust fit of the upper portion against a foot, the lace adjustable between a first position and a second position based at least in part on manipulation of an effective length of the lace. The lower portion can include a mid-sole and an out-sole, and the lower portion can be coupled to the upper portion at the mid-sole. The lacing engine can include a top-loading lace spool to engage a loop of the lace to enable manipulation of the effective length of the lace through rotation of the lace spool, the lacing engine received within a cavity in the lower portion.

A bubble creation device is disposed in a sole of a shoe and include a soapy water container for storing soapy water, a bubble blowing module, and at least one tube having two ends connected to the soapy water container and the bubble blowing module respectively and being in fluid communication therewith. The bubble blowing module includes a channel in a housing and having an outlet open to the atmosphere, and an air inlet open to the atmosphere; a blowing unit in the housing for flowing air from the channel to the outlet; a film forming unit through the outlet and communicating with the at least one tube; a power unit in the housing for supplying power to the blowing unit; and an on/off switch on the sole for controlling an activation of the blowing unit.

Aspects relate to an energy harvesting device adapted for use by an athlete while exercising. The device may utilize a mass of phase-change material to store heat energy, the stored heat energy subsequently converted into electrical energy by one or more thermoelectric generator modules. The energy harvesting device may be integrated into an item of clothing, and such that the mass of phase change material may store heat energy as the item of clothing is laundered.

An article of footwear including an adaptive support system includes a plurality of support members. Each support member includes an outer chamber and an inner chamber, the inner chamber being filled with a magnetorheological fluid. An electromagnet is disposed adjacent to the inner chamber and can be used to vary the viscosity of the magnetorheological fluid.
