I have not skied in a few days and my feet feel back to normal now. I will add that I have flat feet when standing and am very hyper mobile (EDS) so over flexibility has always impacted me. When I ski more on the ball of my foot I feel unsteady/unstable, would you say is this because of EDS, flat feet, or could it be Plantar fasciitis? Sorry for making this so long but I have been fine all summer and now this just came up from no where, so I am a little bewildered.
