Setup, Compatibility & Care
To ensure the best experience, verify your sizing using the UK standard measurements provided; the Endorphin Speed 5 is designed for a performance-oriented fit, so ensure you have roughly a thumbnail's width of space at the toes. When tying the laces, avoid over-tightening the midfoot to maintain proper circulation during longer efforts. For care, do not machine wash these trainers. Instead, use a soft-bristled brush or a damp cloth with mild soap to spot clean the nylon upper and the sole. Allow them to air dry away from direct sunlight or extreme heat, which can damage the foam's structural integrity over time.
