The GlideWear Midfoot Protection sock combines the comfort of a seamless SmartKnit sock with the protection of GlideWear’s patented, low-friction fabric. GlideWear is a two-layer fabric that absorbs harmful friction and shear between its layers, protecting your feet. The non-binding top of the sock fits comfortably around the ankle and works well for people with diabetes. Seams are very flat and strategically placed away from high-risk areas. The result is a comfortable, breathable sock that protects your forefeet from the friction and shear that causes ulcers, blisters, and calluses.
