Size and fit - Note: Please measure your size before purchasing. - How to measure: 1) Keep your legs vertical and do not bend the knees. 2) Find the middle of the knee. 3) Measure the thigh circumference 4 inches (10 cm) above the middle of the knee. 4) Find the appropriate size in the size chart. Protection and thickness - Thicker knee pad: The knee pad is thicker and protects the knee more effectively in case of falls, reducing the impact of collisions and reducing stress and fatigue of your joints and muscles. - Practical use: Basketball and football players as well as other athletes almost always wear knee pads to protect their knees. Comfort and grip - Great comfort with strong grip and non-slip function. - Simply put on the knee pads and forget that you have worn them. - Comfortable to use with no need to constantly adjust as it sits firmly on the knee. Improved fit and protection - Extended length of the sleeves protects your legs from scratches and cuts. - The non-slip material stays in place and does not chafe. Recommended use scenarios - Playing basketball or football, including games and practices, where knee protection reduces impact. - Training sessions or drills involving dynamic movements that stress the knees. - Any athletic activity or workout where knee protection and a secure, comfortable fit are beneficial.
