This is a hands-free knee crutch (like a crutch) that allows for hands-free walking, even with injuries or disabilities below the knee, such as ankle or foot injuries. I needed to immobilize my ankle due to an injury, and since conventional crutches were inconvenient, I used this product. The iWALK2.0 requires caution, such as avoiding falls, when you first start using it, but once you get used to it, you can walk normally, even to the point of being able to jog. 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. Although the cushioning and usability are inferior to the iWALK3.0, it is still perfectly usable. I have recovered from my foot injury and no longer need it, so I am putting it up for sale. - Model Name: iWALK 2.0 - Included: User Guide Thank you for looking.
