This shoe even looks fast when it's sitting still, and if your running preference is for a low-profile shoe, then the Air Alvord V is the shoe you seek. It has everything a trail runner wants, including cushioning, support and flexibility. The breathable mesh upper is equipped with strategically placed overlays for support where it's needed most. Ground shock is soaked up by a full-length Phylon midsole with a caged softion heel crash pad. The placement of the lugs on the outsole design was carefully planned to provide optimal traction and debris-shedding performance with multiple flex grooves for necessary flexibility.
