With shoes designed to accommodate the 33 joints in the foot, the 33 series has been the most nimble of the ASICS running lines. The new 33 FA features the latest version of the Fluid Axis geometry first introduced in the Gel Lyte 33. Here it features a 4mm offset from heel to toe.

The upper is open mesh with soft, sueded overlays that are welded for a smooth interior. The structure is minimal. The midsole is two layers: a Solyte cradle near the ground and a new compound, AmpliFoam, that sits atop the cradle near the foot. While the AmpliFoam’s cushioning has been superior, it needs more structure, hence the cradle. The outersole is AHAR, ASICS’ abrasion-resistant rubber compound, which spreads over the shoe in pod-like segments. The rest of the sole is toughened foam. The outcome is a shoe that’s excellent for faster running, strengthening, and even as a regular training shoe to rotate into your routine.

Testers: “It has a very flexible and comfortable upper. I like the way the shoe flexes and moves with my foot. The flexibility of the toe box makes it very comfortable, almost slipper-like.”
