General Application The 3D Flat Ankle Support is recommended for minor to moderate ankle sprains. Made from Flat Stitching Technology. This allows customized stitching to achieve 3D shaping of the fabric for a optimum fit. 3D Fit contours to ankle area to provide compression and support. Breathable, multi-directional stretch allows full range of motion while maintaining high level of support. 20-30 mmHg, medical grade compression. Design Theory Made from Flat Stitching Technology. This allows customized stitching to achieve 3D shaping of the fabric for a optimum fit. 3D Fit contours to knee area to provide compression and support. Breathable, multi-directional stretch allows full range of motion while maintaining high level of support. 20-30 mmHg, medical grade compression Features Breathable 3D Knee Support breaths and is suitable for warm weather. The knit design provides effective compression without restricting range of motion. 3D Shaping for Optimum Fit Designed with 3D Shaping, rather than standard flat stitching. 3D Flat stitching allows custom levels of compression throughout the brace, creating a more anatomically designed support. ------ Sizing Chart Measurement based on shoe size. If between sizes, order one size down. Made in Taiwan
