The Saucony Grid Fastwitch 4 is a lightweight running shoe designed for racing. Average weight is just 7oz thanks to Saucony's SSL Super Light EVA polymer blend midsole that maximizes durability and rebound while maintaining a low overall mass. The bottom of the shoe or 'outsole', is made of EVA+ high abrasion rubber, and is covered with Saucony's patented XT-900 carbon rubber compound that is made to take a beating on rough surfaces while still maintaining traction. XT-900 sits between XT-600 and XT-1200 grade Saucony outsole rubber. Air meshed material is used on the upper part of the shoe giving breathability to both shoe and foot, as well as keeping the shoe as light as possible. The Grid Fastwitch 4 is used and endorsed by American track and field athlete Anthony Famiglietti.
