The Lone Peak 4 Mid RSM will likely please fans who like a high-top shoe & need protection from rain, snow and mud. This update features a new eVent upper that is 100% waterproof while remaining breathable for comfort across ALL weather conditions. This Mid Mesh version has the same stack height as the previous Lone Peak, stacking up to 25 mm. Altra’s trademark FootShape toe box design carries over to this shoe, giving the wearer room and space in the toe box. The zero drop is also a classic feature from Altra in this trail shoe combined with their FIT4HER technology to conform to the female foot. A DuraTread Rubber with TrailClaw design build the outsole of this shoe, making tread and grip sticky and durable.
