Sipes

Thin slits in a footwear outsole or tire tread to create better traction. True sipes in footwear are those that are cut into an outsole during manufacture. True sipes in tire treads are cut in the tread only after market. True sipes must be flexed to open. Imitation sipes are molded and remain open.
