All rubber flooring is not created equal! Polyurethane-bound crumb rubber flooring is porous and will absorb water and sweat which causes odor and bacteria and which will degrade the floor over time. FitFloor™ products are engineered from 100% high-density, vulcanized recycled rubber. This unique vulcanization manufacturing process means there are no pores for water or sweat to seep into giving you antimicrobial protection and commercial-grade durability. Used in commercial sports complexes, ice rinks, and gyms all across North America for the last 20 years, FitFloor is engineered to last.
