Setup, Compatibility & Care
To get the most out of your Challenger 8s, ensure you have selected the correct UK size for your specific foot shape, noting that the fit has been updated for better security. For maintenance, keep the shoes away from high-heat sources like radiators, as this can degrade the foam and adhesive. After muddy runs, allow the shoes to air dry naturally by removing the insoles and stuffing them with paper towels to absorb excess moisture. Avoid machine washing, which can compromise the mesh and structural integrity of the cushioning.
