product description 1. Visualize your progress - Individually numbered loops will help you see your stretching progress. Contrary to buckle straps, you don't have to stop and adjust the straps for different stretches. 2. It's comfortable and wide enough for your feet to slide in without being tight. 3. Non-elastic and Durable Material - It is made of cotton strap, which is non-elastic, allowing you to use it for many years without deforming or breaking. Can help you build most of your muscles. 4. Helps you gain greater mobility and flexibility. It's a great way to start stretching and physical therapy, even if you've never done it before. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
