A usefull thing to do is to check your weight bearing dorsiflexion. You can do this by standing in front of a wall with your toes 4-6 inches away from the wall, then bend your knee until it touches the wall. if you can do this without your heel coming off the floor move your foot futher back if you are unable then move you foot closer. You want to see how far you can have your foot from the wall and still touch your knee to the wall. try this on both sides and see if it is the same.
