ABSTRACT:
A footwear adapted for anti-skid use, such as on ice or any slippery or hard surfaces, to play a broom ball game or for curling and which includes an outsole of resilient rubber sponge or microcellular rubber or foam material, such as latex or plastic foam, having cavities to allow the outsole to yield in contact with a supporting surface and thereby produce increased traction or antiskidding. This footwear distinctively includes an outsole with cavities opening on the inner face of the outsole and extending in the latter short of the outer face to form a flexible outer wall and yieldable partitions between the cavities with an insole adhered on the inner face of the outsole against these partitions and closing the cavities. These cavities, being sealed by their individual walls and by the insole, produce sealed air spaces which are pushing back the flexible outer wall and protuberances, thus forcing the same to conform to any surface irregularity on which the sole rests.
