Hand-clean uppers with cold water and a soft brush; use a mild detergent only if needed. Do not machine-wash, it degrades adhesives, compresses the midsole foam, and shortens the life of FF Turbo+, FF Turbo² and FF Leap super foams. Do not tumble dry, bleach or dry clean. Rotate between two pairs where possible, PEBA / A-TPU super foams rebound better when given 24 hours to recover between runs. Store at room temperature out of direct sun; heat and UV accelerate foam breakdown. Keep Gore-Tex models clean on the upper to maintain breathability; reproof the face fabric with a water-based DWR when water stops beading. Bundle & Save Build a bundle and save up to 10% off.
