Altra Women's Torin 4 Running Shoe
More responsive midsole
Lower to the ground
Quantic is a lightweight midsole technology that provides plush comfort with a responsive ride.
Inner Flex flex grooves system provides additional flexibility and cuts weight for increased performance.
Foot Shape Toe Box allows the shoe to move with the bones and tendons of the foot.
Natural Ride System (NRS) design includes a more natural, foot-shaped last, zero millimeter heel to toe drop, and metatarsal-specific shapes in the outsole to assist in proper foot mechanics and allow for more natural foot movement.
FootPod Outsole follows the natural construction of the human foot for a responsive ride, updated to improve flexibility through the gait cycle.
Performance Air Mesh is updated to provide maximum comfort and breathability in a lightweight design
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.
