The Asics Women's Gel-FujiEndurance Trail Running Shoe is a versatile choice for hitting the dirt regardless of the conditions. Asics' new PlasmaGuard upper sheds rainfall and mud yet remains breathable for warm, sunny weather. The removable ComforDry X-40 sockliner breathes, wicks moisture, and enhances rebound energy at each step. The Gel-FujiEndurance follows Asics' Impact Guidance System to give a natural gait for runners with neutral to under pronation rolls. There's a shock-attenuating Gel Cushioning System at the heel, and the Rock Protection Plate prevents bruising under the entire sole. Asics made the sole with highly abrasion-resistant rubber, and the Trusstic System saves weight by reducing rubber in key areas. PlasmaGuard upper. Removable ComforDry X-40 sockliner.
