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.
