  • For Neoprene or Supplex/Lycra: choose the sleeve length that matches your brace coverage from thigh to calf. The undersleeve should fully cover the skin beneath your brace for complete protection.

How to Wear / Fit

  1. Slide the undersleeve over your foot and pull it up so it fully covers the area under your knee brace
  2. For open-patella Neoprene, align the opening over your kneecap
  3. for closed-patella styles, center the knee under the sleeve
  4. Smooth out wrinkles so the sleeve lies flat against the skin
  5. Apply your knee brace over the sleeve and recheck comfort while standing and walking.
