A walking aid worn below the knee, allowing the user to have both hands free. I used this when I fractured my leg. Thanks to this, I was able to go out walking even though I couldn't use one leg. It's a truly appreciated item. It was overwhelmingly easier to use than crutches, as I could use both hands. It shows signs of use, but it works without any problems. Please forgive some dirt (on the sole). - Model Name: iWALK 3.0 - Color: Blue and Black - Purpose: Walking aid - Design: Below-the-knee type - Features: Allows both hands to be free Thank you for looking.
