One piece black rubberized construction with steel spikes on bottom at ball of foot. Steel spikes press into the ice and snow to offer stable, secure traction. Helps prevent spills on icy and slippery surfaces. No straps or buckles - grippers stretch to accommodate nearly any type of footwear, from running shoes to winter boots. One size fits most - grippers stretch from toe to heel over most footwear. Low-profile design makes it easy to walk naturally. Hang packaged.
