iWalk 2.0 Hands Free Crutch (with user manual and extra knee pad) - $80

"iWalk 2.0 is a Hands Free Crutch that is so easy to use that most people adapt within 2-3 minutes. ..... This alternative crutch is designed to allow a person with a
foot or ankle injury free use of there hands and full mobility."

I used this during the 10 weeks I was unable to put weight on my left foot after surgery. It was the only device that allowed me to safely get up and down the stairs to my apartment, to cook meals, and to go shopping. I used it in combination with a knee scooter and was able to comfortably do most things I do normally.
