A shoe insole which, within a shoe, combines shock cushioning, heat dissipating, moisture-removing, and low-frictioning contact with the underside of the foot. The insole preferably includes two adhesively bonded layers. The lower layer is a shock-cushioning layer which includes plural, elongate, through-bore perforations that are distributed in a grid fashion throughout the layer, with each perforation extending completely through the thickness of this lower layer, and opening to opposite (upper and lower) faces in the lower layer. The upper layer is a continuous, non-perforated moisture-wicking, low-frictioning, fabric layer which extends across and spans the upper, otherwise open ends of the perforations.
