“A 2013 study found that people with limited dorsiflexion (capacity to flex the foot towards the shin) suffered from an altered gait that put undue strain on their knee joints. Another showed that ankle instability led to a reduced range of motion in the knees — a major cause of non-contact injury in sports.” So the pain or strain you might be feeling in the knees, could actually be your ankles. This is why ankle strength and mobility is so important. Stretching and ankle exercises are a great way to strengthen them and prevent injury that could have been avoided.
