The Nike Pegasus Trail 5 requires no special setup beyond ensuring a proper fit. Choose your standard UK shoe size for Nike footwear; if unsure, refer to a Nike sizing chart. These shoes are compatible with various trail running apparel and gear, including running socks designed to prevent blisters and gaiters for very muddy or sandy conditions. To care for your shoes, brush off loose dirt and debris after each run. For deeper cleaning, hand wash with mild soap and water, avoiding harsh chemicals. Allow the shoes to air dry naturally at room temperature, away from direct heat or sunlight, which can damage materials. Remove insoles to air out separately if needed. Proper care will help maintain the shoe's performance, appearance, and extend its lifespan.
