Abstract
A shoe, particularly an athletic shoe, in which a multilayer assembly is disposed between the midsole and the insole of the shoe, with the multilayer assembly inhibiting the transfer of heat by virtue of a heat resistant layer or film disposed within the multilayer assembly. The multilayer assembly preferably includes a metalized Mylar (polyethylene terepthalate) film which is sandwiched between two layers of strobel material. This arrangement provides an effective and durable design which inhibits the transfer of heat from hot surfaces to the foot. In accordance with a further aspect, an advantageous ventilation system is provided in the insole, with the ventilation system particularly effective since it is shielded from heat utilizing the multilayer assembly.
