During leg workouts and running the Edge feels great. It does have a tendency to migrate down the leg slightly while running though. Smooth fluid motion in the hinges and the straps have never once pinched my leg. When you reach full extension the brace snaps abruptly and assures you that it will not go any further, very reassuring. The knee sleeve that is worn under the brace is very comfortable for the first hour or so after that it gets HOT. Even at rest the sleeve will cause your leg to become hot and sweaty. I have stopped using the sleeve all together. It is almost as comfortable without and MUCH cooler.
