The Altra Torin 4 had been updated to be quicker and more reactive than ever before. Designed for fast-paced endeavors, the Torin 4 features Altra's new highly responsive Quantic midsole and a closer to the ground feel. By removing the Strobel layer underfoot, Altra decreased the stack height of the Torin 4 by 2mm and created a faster, more flexible shoe. The Torin 4 provides a secure fit while settling the foot deep inside of the shoe for a wonderful connection to the road as you conquer the miles of your next run.
