Altra Women's Lone Peak 4.5 Lightweight Trail Running Shoes

The updated version of our original trail shoe features a trimmed down layer that offers added flexibility and comfort and a simplified lacing system for improved micro-adjustment. Like all previous versions, the Lone Peak 4.5 includes all of the Altra trail shoe must-haves like StoneGuard™, MaxTrac, Balanced Cushioning and the FootShape™ toe box. To top off the update, the midsole foam formula has been tweaked just enough to give you a more resilient feel underfoot. Insole: 5 mm Contour Footbed Midsole: Dual Layer EVA / A-Bound with StoneGuard™ Outsole: MaxTrac Rubber with TrailClaw™ Cushion: Moderate Upper: Durable Quick-Dry Air Mesh
