Adhesive Callus & Ulcer Prevention


  • Applies directly to footwear, insoles, orthopedic braces, or athletic equipment – not against the skin
  • Patented technology provides immediate relief and long-lasting skin protection
  • Easy peel & stick application. No secondary adhesive required.
  • Ultra-thin profile (0.38mm) doesn’t alter shoe & device fit


ShearBan’s patented ultra-low friction PTFE film with durable self-adhesive backing provides long-lasting protection from skin abrasion, calluses, corns, blisters, bunions, and foot ulceration. ShearBan is ideal for patching troublesome areas of orthopedic braces, prosthetic sockets, footwear, insoles, athletic equipment, and more. Available in 8″ x 12″ sheets, Rivet Cover & Cosmetic Patches (for concealing hardware), and individually-packaged 1.75″ x 2.75″ patches.

Target Rubbing at the Source!

ShearBan works by reducing friction only in specific, at-risk areas of footwear, insoles, medical devices and sports equipment to protect sensitive tissue from wound formation. Friction is retained in surrounding areas to optimize mobility and stability for users.

ShearBan Works To:

  • Enhance comfort and extend the user’s ability to walk, run, work, and play each day
  • Provide a greater margin of safety for individuals who are highly susceptible to skin breakdown; especially individuals with neuropathic foot conditions, amputations, or foot deformities
  • Maximize orthopedic support and correction beyond what’s possible with pressure offloading alone due to the reduction in tissue deformation where ShearBan is used
  • Prevent recurrence of skin breakdown, since ShearBan does not require re-application after initial placement. ShearBan lasts many months before replacement may be necessary.

Sold in Four Convenient Purchase Options:

  • 1.75″ x 2.75″ patches for easy installation by consumers wanting to “spot relieve” areas of irritation or skin breakdown
  • 8″ x 12″ sheets, ideal for custom trimming and installation
  • 3/4″ and 1″ Rivet Cover Patches for concealing strap hardware on orthopedic braces to prevent  skin contact and metal corrosion, and to provide an attractive finished look
  • Cosmetic Patches to create a smooth, cosmetically-appealing finish over externally mounted joints within upper and lower extremity braces

Product Instructions

  1. Trim sheet to desired patch size.
  2. Remove half of the patch from the backing, using the backing to create a tab.
  3. Apply adhesive side of ShearBan patch to desired location of clean, dry location.
    Tip: ShearBan may last longer when anchored to a surface. For example, wrapping patches around the edge/sides of the insole.
  4. Peel remaining backing away from patch.
    Tip: If blisters form at interface of footwear & insole, use two patches. One patch is placed on the footwear. The other patch is placed on the insole. A smooth interface is created.
  5. Press firmly around entire patch surface to secure.
