Setup, Compatibility & Care
Setup: To ensure the best fit, lace the trainers snugly but comfortably across the bridge of your foot. Since these are standard UK sizing, ensure you have a thumbnail's width of space between your longest toe and the front of the shoe to prevent discomfort during extended runs.
Compatibility: These shoes are optimized for asphalt, concrete, and synthetic road surfaces. They are not recommended for muddy or loose gravel trails.
Care: Keep your 680v9s clean by wiping the upper mesh with a damp cloth after particularly dirty runs. Avoid submerging them in a washing machine, as this can degrade the foam cushioning. If they become wet inside, stuff them with dry newspaper and let them air dry away from direct heat sources to preserve the adhesive and material flexibility.
