You’ll definitely need to talk with your doctor if you think you might be in need of a walker boot, often referred to as a walking brace. The reason we suggest you talk to your doctor is you could have a small fracture and not even realize it, so x-rays are typically needed to properly diagnose your injury.
That being said, there is a variety of walking braces and supports available on the market, each designed for different ailments and different treatments. For instance, someone suffering from a foot trauma can wear a walking brace after the operation to help it heal. There are also walking supports designed to provide stability to ankles damaged by acute sprains.
