Our Verdict
Altra Torin 7
ASICS GEL-KAYANO 31
The Altra Torin 7 and the ASICS GEL-KAYANO 31 are both daily trainers emphasizing stability, catering to runners seeking support during their runs. The Torin 7 offers even higher stability, thanks in large part to its lower stack height. However, this means less cushioning, and the KAYANO 31 is the more protective shoe. Another key difference is the heel-to-toe drop: the ASICS features a high drop, whereas the Altra offers a zero-drop platform.
