These trail runners are ready for use right out of the box. Simply lace them up with the `standard tie` system to achieve a snug, comfortable fit before hitting the trails. They are compatible with `NEUTRAL` runners, meaning those who do not require significant arch support or motion control and whose feet roll inward minimally. The shoes are specifically designed for performance on `trail surfaces`. To care for your Under Armour Infinite Pro Trail Runners, it's recommended to clean them after each muddy or dirty run. Gently brush off loose dirt, then use a mild soap and cold water with a soft brush or cloth to clean the upper and outsole. Avoid harsh detergents or machine washing, as this can damage materials. Allow them to air dry completely at room temperature, away from direct heat or sunlight, which can warp materials. Storing them in a cool, dry place will help maintain their integrity and longevity.
