Each tile is made with 75% recycled rubber, including Nike Grind rubber. The tiles are designed to provide the requisite resilience and cushioning for a safer and comfortable exercise session. As a natural sound dampener, the rubber tiles will cut back on the noise and vibration. The tiles feature randomly distributed colors, reflecting excess material collected during Nike footwear manufacturing. Designed with an interlocking edge pattern you have unlimited options in terms of the shape and size of your fitness surface. Each unit comes with 6 tiles and enough edges and corners to cover a total surface area of 14.32 sq. ft. You can join multiple packs together to cover any shape or size exercise room. The modular construction allows you to cover around corners without any cutting and trimming, while the straight edges give the tiles a finished look. Color: Multi Colored Specs/ Light Gray Base.
