Ankle braces can prevent injuries to a certain extent during exercise. It is not that you can wear ankle braces without scruples. You will still be injured in large collisions, etc., so self-protection is more important. The ankle pads used in sports need to be under good pressure and can tighten the ankle joints. They are loose and have no effect, so you have to choose the model that suits you.
There are two kinds of ankle brace, one is an adjustable pulling belt type ankle brace, and one is a fixed type strap ankle guard.
