ALTRA. ALM1937F232. MENS TORIN 4. GREY WITH LIME. We ve taken the fan-favorite Torin and tuned it for the racecourse. We have added the new Altra Quantic midsole and removed the strobel layer with results in 2mm less cushion height than the Torin 4 Plush for a lighter faster and more responsive Torin. The strategic decoupling on the outsole gives you a flexible but smooth ride throughout and with a lightweight performance mesh this shoe is ready for spirited miles.
