Gently used Altra Olympus. Uppers do have some marks from being used in muddy/rocky terrain, but the shoes have only been worn for about 20 miles, so they're functionally pretty close to new. Photos show the most obvious signs of wear. Some additional marks may be present that I didn't catch, but the pics give you an idea of the overall condition. Features: -Balanced Cushioning places the heel and forefoot at equal distance from the ground to promote proper, low-impact form throughout the run. -Engineered mesh upper provides enhanced breathability and airflow for all-day comfort. -Lightly-padded tongue and collar with flat laces that allows traditional lace-up closure. -GAITERTRAP™ hook-and-loop tab allows strapless gaiter attachment that prevents debris build-up beneath the shoe. -Stack height of 33mm provides ample cushion for long runs -FootShape™ toe box allows your toes to relax and spread naturally for more comfort and stability during uphill climbs and downhill descents. -Highly-responsive EVA midsole with InnerFlex™ flexible grooves delivers more speed and improved performance. -Vibram® MegaGrip® rubber outsole with TrailClaw™ canted lugs positioned strategically beneath the metatarsals to provide traction at the toe off.
