Otto Bock’s Derma Seal Residual Limb Socks are coated with a special polymer gel for comfort and durability.

The Derma Seal Residual Limb Socks are ideally suited for transtibial amputees. The socks are coated with a special polymer gel. The sock’s viscous properties reduce irritating friction, pressure, and stress on the skin.
Select from a variety of styles to suit your patient’s needs. The Derma Seal 453D7 is uniquely designed to protect against friction, impacts, and pressure. The Derma Seal Forte 453D4 is made for high-activity amputees. The CoolMax® fabric increases toughness and the level of wearer comfort.
For highly active customers and for bony residual limbs, the Derma Seal Double Forte 453D5 is available. With this very durable model, the polymer gel is enclosed between two layers of CoolMax® fabric. We offer the Derma Seal Trans Ped 453D2 especially for Lisfranc and Chopart partial foot amputees. This sock is knitted without seams and consists of 95 percent polyester and 5 percent Lycra® Spandex. The distal area has an interior coating of polymer gel and therefore provides targeted protection against friction, pressure, and stress for these skin areas.
The special Derma system is available for skin care and prevention. The products protect and care for severely stressed skin. At the same time, natural immune and protective functions are regenerated.
