The legendary durability of Tuff Toe Pro's rubberized epoxy material has made it the overwhelming choice of professional, collegiate and recreational pitchers since 1979. Tuff Toe Pro is applied as a thick liquid and cures to a durable yet flexible protective layer. The material forms a permanent bond to any footwear, new or used. A dual-chamber mixing cartridge makes application quick and easy. One cartridge coats one to two cleats.
