The Altra® Torin 4 running shoes are back and have been re-tooled for performance and speed. This lighter version features the new Altra Quantic™ midsole and no longer has the strobel layer, helping to reduce 2mm of height from the shoe. The result is a more connected and responsive, lighter weight shoe. A new last promotes a faster, livelier running experience.

Upper: Updated, mesh upper with TPU overlays provides lightweight, breathable support. Integrated tongue offers a more secure fit.

Midsole: A Zero Drop™ platform with a FootShape™ toe box allows the toes to relax and spread out naturally and the big toe to remain in a straight position for more stability and powerful toe-off to maximize running performance. Innerflex™ provides grid-like grooves in the midsole allow your foot to flex while being lighter, for more speed and better performance. Quantic™ midsole for a fast, light, and responsive performance.

Outsole: Features strategic decoupling on the outsole to give a flexible and smooth ride.
