Get ready for a totally revamped shoe with Altra’s Timp 4. This shoe is rugged. The Timp 4 is a road to trail shoe that will take you from your doorstep, to the top of Tungsten Peak and back. This newest edition now has the EGO midsole, which has maximum cushion and a propelling bounce to make your stride feel effortless. The forefoot and upper are totally redone with an abrasion-resistant mesh and the toe-box has more water-resistance. The outsole is Altra’s trademark Max-Trac, so you’ll be able to tackle any terrain in the Sierras.
