A breathable, impermeable and elastically compliant composite insole (1) equips a bottom (2) of an item of footwear (18) having a ventilated foot space (13) and whose bottom (2) comprises an outsole (3) having holes (4) running through it for aerating the foot space (13). The insole (1) has a multilayer structure comprising a first layer (5) of microperforated, semirigid osmotic material, and a second layer (6) of macroperforated, soft impermeable material which are made to adhere monolithically, superposed over each other. The second layer (6) is larger in surface area than the first layer (5) and forms, in combination with the latter, a continuous border (7) which extends past the edge of the first layer (5) and which peripherally surrounds the first layer (5) itself. A ventilating bottom (2) and an item of ventilated footwear (18) form part of this invention. |
