It's waterproof. It's grippy. And it's cushioned. This is trail running in the new Timp 5 GTX. We built it with the same comfort you love, ready for any condition. Keep your feet dry with a GORE-TEX upper, tested and proven for durably waterproof, windproof, and breathable performance, backed by the GORE-TEX GUARANTEED TO KEEP YOU DRY promise. Unlock the magic of rowdy terrain with a Vibram Megagrip outsole, for grip on both wet and dry surfaces. Stay comfortable on the toughest of trails with an updated Altra EGO MAX midsole foam compound. It's designed for luxurious performance with a little extra bounce and added durability. The new Timp 5 GTX gives you a roomy toe box and zero drop, with plenty of room to help your toes move more freely and a secure midfoot. Make dust clouds. Splash puddles. Stay Out There.
