Setup, Compatibility & Care
To ensure the best experience with your Challenger 8s, verify your size using the UK standard sizing provided. Because of the 'sock-like' fit, it is recommended to wear thin-to-medium thickness athletic socks to prevent constriction. For care, keep the shoes away from heavy mud if possible, as the mesh can trap debris. If they become dirty, wipe the TPU overlays with a damp cloth and gently scrub the mesh with a soft brush and mild soap. Never machine wash or machine dry these shoes, as the heat and agitation can degrade the cushioning materials and weaken the adhesives holding the sole and upper together. Allow them to air dry naturally, away from direct heat sources like radiators.
