Altra's original trail shoe gets some fresh new updates to make this version better than ever! First off, the upper is not only more breathable but more durable and secure, it features a static webbing cinch strap at the midfoot, a sandpaper textured toe cap, and improved drainage holes. The outsole gets a complete makeover with decoupled TrailClaw(TM) and multi-directional, carved lugs for increased traction and reduced weight. And just in case all the new features didn't already have you stoked, the StoneGuard(TM) is completely new and now resembles the skeletal structure of a foot for dynamic flexibility and better performance. Features: - Quick-Dry Air Mesh upper - Balanced cushioning and zero drop design encourages proper, low-impact form - Footshape toebox allows your toes to relax and spread out naturally for more comfort and stability in uphill climbs and downhill descents. - Women's-specific fit - Dual-layer EVA/A-Bound midsole - Trailclaw canted lugs are positioned strategically beneath the metatarsals to provide traction at toe off. - GaiterTrap hook-and-loop trap allows strapless gaiter attachment - 5mm Contour Footbed - Stack Height: 25mm - Weight: 8.5oz / 241g
