It's about to get wild. With a shoe that's got Vibram(R) grip and a lightweight feel, get ready to achieve trail running euphoria. We took the beloved Experience Wild 3 and added a Vibram(R) Megagrip outsole with Traction Lug and an integrated toe bumper, designed for increased grip on all terrain. With the new Altra EGO(TM) P35 midsole foam, it's a shoe made for a light & efficient ride. It's got a redesigned heel collar and updated fit construction for a more comfortable, secure feel. With the Altra Fit, you get room for your toes and a secure midfoot for natural movement. A low 4mm drop with rocker shape geometry helps promote natural body alignment and an efficient toe-off. Easily attach a Trail Gaiter, made to help keep your feet clean from debris, with an integrated GaiterTrap(TM) detail. Responsive. Effortless. And seriously grippy. It's no wonder the Experience Wild 3+ is ideal for a trip in the woods.
