Abstract
A composite footwear insole has a front portion (2) designed to interact with the foot at the metatarsal region and at least partly at the plantar arch, and a rear portion (3) designed to interact with the heel. The rear portion (3) has at least one layer (4) of gel material whose size is at least substantially equal to that of the rear portion (3) to uniformly support the heel and absorb stresses acting thereon.
