Classic heel raises are not a bad starting point for exploring ways to mobilize your foot. When doing them, your forefoot changes its shape while being under the load of your body, which is quite a functional setup. Not to mention a nice workout for calf muscles. But if you really want to focus on the mobility aspect, instead of climbing up, try raising your heels by pushing your knees forward while keeping your pelvis in place. This version brings your heel more forward, allowing for greater bending leverage on the toes while simultaneously achieving more plantarflexion in the ankle. This combination works for the foot like squeezing a towel from both sides, because now tissues have to decide whether to move towards the stretched front of the ankle or towards the equally stretched bottom of the forefoot. If doing this you hear clicking and popping sounds from your foot, don't worry. That's the sound of your body regaining mobility. #footmobility
