I was recently diagnosed with a talus coalition in both of my feet. In each foot, the talus is fused to the calcaneus. The right foot is worse than the left foot, but the problem definitely exists in both feet. This prohibits me from achieving anything more than few degrees of dorsiflexion in both feet along with only a few degrees of pronation and supination. Because of this, I cannot squat without turning my feet out very wide. Wearing lifting shoes helps to compensate for the problem, but only a little. I would estimate that to achieve a proper squat in lifting shoes, I have to position my feet at about a 90 degree angle, if not wider. I cannot keep my feet pointed forward in a squat position. Also, to achieve any outward knee drive in a squat, I have to continue to rotate my feet to compensate for the lack of ankle mobility.
