Silicone pads distribute the load on the knee, reducing stress on the meniscus. It has the durability to withstand movements like volleyball and running, supporting joint stability. 【Anti-Slip Design for Long-Lasting Fit】The beister knee support uses high-density silicone on the edges to prevent slippage and detachment during exercise. With the fixing power of medical supports, it can be used with confidence by the elderly during daily walking and climbing stairs. 【Comfort Maintained with Excellent Heat Retention】The beister knee support uses a dense material to retain warmth around the knee, mitigating the effects of cold air during outdoor sports (running, hiking), daily commutes, and climbing stairs. It is also designed to prevent excessive warmth in indoor environments, providing stable heat retention in situations with temperature differences. 【Versatile Use】This knee support can be used for various sports and daily life activities, including running, weightlifting, basketball, tennis, and volleyball. It is designed for men and women, and the elderly, meeting the needs of a wide range of users.
