Setup, Compatibility & Care
To ensure the best experience, start by wearing your Ultrarun 5s with athletic socks that wick moisture away from the skin. Use the standard lace-up fastening to achieve a secure fit that locks your heel into the padded cuff without overtightening. Because the upper is primarily textile and mesh, avoid wearing these in heavy mud or excessive water to keep them clean. For care, remove the OrthoLite sockliner after particularly sweaty runs to air out separately. If the exterior gets dirty, gently wipe the mesh with a damp cloth and mild soap; do not machine wash or tumble dry, as high heat can compromise the integrity of the Bounce foam and the adhesive materials.
