You can jump, run and move freely with this product. It was a bit confusing to pick a size but they guided me during the process. The package arrived fast and in great condition. I recommend them.
Just purchased the sports ankle support from Jaiyou suggested by my friend. It sure supports your ankle during my long runs. I no longer need to worry about my ankle pain during workouts. Awesome from Jaiyou.
This is an excellent product! I wore it every day for a year and had no problems with it until I placed it in the dryer (which you shouldn't do). Aside from that, it's so good that I'm going to upgrade to the latest ankle support. Keep your ankles safe!
