The Silipos Symes Gel Liner is intended for amputees with a Symes amputation. The Symes Gel Liner can replace your existing 5 ply sock with its gel coated and Coolmax construction. This symes gel sock can protect and cushion your shin bone while providing a nourishing environment that conditions the skin. The Symes Gel Liner conforms around bony areas, minimizes skin breakdown, and reduces friction, shearing, and abrasion. Silipos Symes' Gel Liner is extremely durable because Silipos’s patented gel is now bonded to a resilient fabric that is washable, reusable and resists gel delamination.
