The ASICS Men's Fuji Speed Trail Running Shoes with ASICSGRIP Technology are made to stride varying trails at any speed. These shoes have an asymmetrical lacing system that reduces pressure across the top of the foot while the lace garage system keeps laces from coming untied as you run. The FLYTEFOAM cushioning absorbs impact while the Pebax propulsion plate helps you perform at your highest ability by redirecting your energy forward.
