As Shirley Sahrman says, the body will naturally take the path of least resistance and the knee will end up inside of the foot in a deep squat when your body requires extra ankle motion to get deeper into the squat. Check the video below for a better explanation.
Why Do People "Toe Out" or Have Their Knees "Fall In" at the Bottom of the Squat When they Have Stiff Ankles? I think most people understand we want to have ankle mobility but the "why" component is sometimes missing. Here is a major reason why stiff ankles cause toe out. People will often have much more ankle dorsiflexion with their knee facing the inside of the foot then outside (try it out yourself). This forces toe out in a deep squat. Stiff ankles can also lead to a shallow squat, low back rounding, excessive hip flexion on the stiff side, knee tracking issues and increased hip internal rotation, all of which may not be ideal when squatting. Obviously we want to address this.
