The Patagonia Ranger Smith Shoes are comfortable walk-around shoe with a simple design using eco-friendly materials.

A 100% recycled polyethylene/polyurethane shank protects and supports on rough trails and under load. Partially recycled air cushion midsoles soften the ride. Cork footbeds incorporate active carbon to reduce foot funk. Ankle-height Polartec linings and dri-lex backed wool footbed linings provide moisture and temperature control.
