They were used on a rug to learn how to use them and have never been outdoors.
SmartCrutches are currently not being sold. These are a great forearm crutch and the arm rests can be adjusted to different angles. I found them pretty easy to use, but my surgery was canceled. Perfect for hypermobility, wrist, and shoulder injuries. The color is circled in the photo.
Purchased for $229. Asking $125 OBO. Pick up in NYC or buyer pays shipping.
