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.

Various embodiments are directed to an adjustable insole for a footwear article. In various embodiments, the adjustable insole comprises an insole body comprising a heel bottom cavity defined by a cavity opening provided along an insole body bottom surface; and a removeable heel bottom insert configured to be disposed within the heel bottom cavity such that a first insert portion is disposed within the heel bottom cavity and a second insert portion defines a lowermost surface of the adjustable insole, the removeable heel bottom insert having a selectively adjustable configuration relative to the insole body that is defined by an arrangement of the removeable heel bottom insert within the heel bottom cavity in one of a nominal position and a rotated position defined relative to the nominal position by a rotation of the removeable heel bottom insert through an angle of rotation of at least approximately 90 degrees.

The present invention relates to a fatigue-reducing safety shoe. The shoe according to the present invention is able to offer the user a high degree of protection in case of accidental events, in accordance with current regulations, together with a higher level of comfort perceived by the user due to a specific configuration of the multilayer sole capable of respecting the ergonomics of the user according to the biomechanics of the walk.

An insulating shoe insert, as for use in an athletic shoe, comprises a core layer to cushion and to resist moisture, comprising a honeycomb-like cellular material, and a top layer and a bottom layer positioned on opposing sides of the core layer, the top layer and bottom layer to resist the transfer of heat through the insulating shoe insert. The top layer and bottom layer comprise an aromatic polyamide, in some embodiments a long-chain synthetic polyamide in which at least 85% of the amide linkages are attached directly to two aromatic rings, in some specific embodiments NOMEX or a similar meta amarid material. The core layer generally includes a honeycomb-like cellular material with irregularly shaped and spaced cells, often a vegetable-based honeycomb-like cellular material. The top layer and bottom layer are bonded to the core layer by an adhesive.
