éThe Asics Men's 33-FA Running Shoe makes it easier to extend your daily runs with as many miles as you see fit. Built on Asics' Natural33 last, the 33-FA mimics the shape of your foot for a secure fit that still allows toe movement. The seamless upper reduces irritation and friction for going over your usual mileage, and the ComforDry sockliner offers extra cush, anti-odor freshness, and a cooler, drier and healthier environment. Underfoot, Asics equipped the 33-FA with a, "so-light," Solyte midsole for a surprising amount of cushioning that's sure to last. Asics High Abrasion Rubber makes the sole last a long time too, and FluidAxis grooves align with the joints of your foot for excellent flexibility. FluidAxis also enables the shoe to adapt and respond to your specific running style for a customized performance that you'll notice.é
