The Pro-Tec 3D Flat Calf Support uses 3D Flat stitching technology to create 3D shaping of the fabric itself, making for a contoured fit around the calf that provides more comfort, more support, and a greater range of motion than the usual brace or support. This support is best used for minor to moderate calf tightness and strains, and provides 20-30 mmHg of medical grade compression.
