The Timp 4 is all-new and ready to tackle any terrain in the Sierras. This revamped edition is the road to trail shoe that will take you from your doorstep to summit and back again. With the newly added EGO midsole, you will have a softer, more cushioned ride but also more spring and energy. The upper now has more protective water resistance and an abrasion-resistant mesh so you can move effortlessly across rugged terrain. And of course, Altra’s trademark Max-Trac outsole will grip onto every surface so you can take on any peak.
