Setup, Compatibility & Care
To ensure the best fit, allow for a small amount of space in the toe box, as feet tend to swell during longer runs. The Challenger 8 features a standard lacing system; ensure the laces are secure but not restrictive to maintain circulation. For care, avoid machine washing or drying, as high temperatures can compromise the integrity of the foam cushioning and adhesives. Instead, clean the exterior with a soft brush and lukewarm water. Remove the insoles after wet runs to air-dry naturally away from direct heat sources to prevent material warping.
