This is a hands-free knee crutch (like a crutch) that allows you to walk without using your hands, even if you have injuries or disabilities below the knee, such as on your ankle or the top of your foot. I needed to immobilize my ankle due to an injury, and since conventional crutches were inconvenient, I used this product. With the iWALK3.0, you need to be careful about falling when you first start using it, but once you get used to it, you can walk normally, even to the point of jogging. Because both hands are free, I was able to live without feeling much inconvenience in my daily life, so this product was a great help. My foot has healed and I no longer need it, so I am putting it up for sale. - Model Name: iWALK 3.0 - Included Items: User Guide Thank you for looking.
