The following is the manufacturer's product description: 【Performance Improvement with Gradual Compression】 The design that gradually applies pressure from the ankle to the calf suppresses unnecessary muscle vibration. It maximizes performance during running and mountain climbing through muscle fatigue reduction and support. 【Excellent Sweat Absorption, Quick Drying, and Breathability】 High-performance sweat-absorbent and quick-drying material is used to quickly absorb and disperse sweat during exercise. It is not stuffy and maintains a constantly dry and comfortable feel, so you won't feel stressed even after long hours of use. 【Excellent Fit with 3D Design】 The three-dimensional 3D design that matches the calf line provides an exquisite hold that fits snugly but doesn't constrict too much. It does not easily slip even with intense movements and provides a stable wearing feeling. 【Ultra-lightweight and Highly Elastic for Stress-Free Use】 It is surprisingly light and uses highly elastic material, so it feels so light that you forget you are wearing it. It is easy to put on and take off and fits a wide range of body types, regardless of gender. 【Choose from 3 Color Variations】 Available in 3 colors: black, gray, and blue. You can enjoy coordinating with sportswear, and colors that enhance visibility at night are also available.
