<p>A structure (10) for ventilating a toe region (13) of a shoe includes a body (11) including in its heel zone (12) two major walls and a resilient element (28) having a multitude of voids (30,31) arranged in a pumping chamber (22) to urge the two walls apart against the action of external forces tending to draw air into the chamber. The resilient element includes a plurality of substantially dome-shaped hollow protuberances (29) bounding respective first (30) and second (31) voids within and outside of them, respectively, and connecting portions (32) that interconnect the protuberances. Respective connecting channels (33,34) are provided in the connecting portions and in respective adjacent regions of the protuberances to establish communication between the first voids. A corrugated insert within the body aids ventilation and shock absorption. An extension on the body optimizes air transfer.</p> |
