If you love the Torin and love running fast, this may just be your favorite Torin yet! The Torin 4 takes our fan-favorite and tunes it for race day. The brand new Altra Quantic midsole is both lightweight and cushioned; we removed the strobel layer for 2mm less cushion/height than the all new Torin 4 Plush for a lighter, faster and more responsive ride. And with strategic decoupling on the outsole you get a flexible yet smooth ride coupled with a lightweight performance mesh, perfect for quick miles.
