How to use: Put on the shoes by opening the single wide closure strap. Slide your feet in and adjust the strap for a snug fit. Make sure your feet are centered in the shoes. When you reach the transition zone in a triathlon, quickly open the strap to take off the shoes or close it to put them on. Note: Don't overtighten the strap as it may cause discomfort during the race. Avoid wearing the shoes in extremely muddy or wet conditions for a long time. Maintenance: After each use, wipe the shoes with a clean, dry cloth. If they get dirty, you can gently wash them with mild soap and water. Let them air - dry naturally, away from direct heat sources.
