Wow, this is fantastic stuff. I think it will be of use to humanity. I wish they'd come up with CAM boots https://dunbarmedical.com/product-category/braces-and-supports/walking-boot/ with the same technology. After my injury, I can't do without these boots. I love skateboarding, and it's been a hobby of mine since I was a teenager. So one day, I decided to practice a new trick that I saw on the Internet. At first, there was insurance in the form of friends, and when I thought I had perfected the trick. I decided to do it myself, but unfortunately, it didn't go according to my plan, and I landed on my foot wrong and broke my ankle. I will have to walk around with a shoe on for a month and wait for it to heal. Take care of yourself and your health!
