To keep your goggles in top shape, never touch the inside of the lens; there's a super delicate anti-fog coating that can be damaged with even the lightest touch. Always store them in a soft bag, avoid placing them face-down, and let them air dry naturally after use. Steer clear of heaters or humid spots to keep them clear for your next run.
