A footlet (1) is provided with a heel portion (2), a toe portion (6) and a middle portion (4) interposed between the heel portion and the toe portion. The middle portion comprises lateral sides extending between the heel portion and the toe portion on either side. The footlet is completely manufactured by reciprocating knitting. The heel portion is provided with a thread comprising an anti-slip agent, which thread is incorporated in the heel portion by knitting.

The present disclosure relates to an insole including a lower layer, an upper layer and an intermediate layer arranged between the lower layer and the upper layer. The lower layer or base of the insole is a supporting layer designed to be placed, in use conditions of the insole, above a sole of an item of footwear. The upper layer is designed to be placed, in use conditions of the insole, in contact with a foot, with or without a sock, of a user. The intermediate layer includes natural feathers distributed uniformly and treated so as not to allow displacement thereof along the intermediate layer. The disclosure further relates to an upper of an item of footwear.

The implementation improves in the best possible way the integration between the insole and a modified sock, different than those currently known. The present implementation describes an insole-sock type insert for shoes, which presents a novel configuration that consists of an insole, which has a short, medium, or modified sock attached to it, totally or partially, within the extension of the insole; a short, medium, or modified sock, partially attached to the insole, remaining loose or free in the front part where the toes go and/or part of the instep as well as the front part of the foot, and; an attachment mechanism between the insole and the short, medium, or modified sock, which allows for their attachment, where such mechanism is a seam, Velcro, adhesive, or any other type of method that has the same function.

Embodiments are directed to an insole for footwear. The insole preferably includes a bottom surface, a peripheral sidewall, and a relief. The bottom surface has a perimeter, and the peripheral sidewall preferably extends upward from the perimeter of the bottom surface. The relief is preferably disposed in the peripheral sidewall.

The disclosure provides an electricity generating insert for a piece of footwear, the insert can be removably placed in the heel portion, e.g. under the insole. The insert comprises a multilayer piezoelectric stack that alternatively flexes under the compression-decompression that occurs during locomotion, which flexing causes friction in the stack to generate electricity capable of charging electronic devices and the like, e.g. via a port on the footwear.
