Since I ruptured my achilles last week, I've had plenty of time to think about things and what happened. I'm a right foot forward skier and I snapped my left achilles. So in my case, my rear achilles. The question I have been asking myself is did having a double boot help cause my achilles to rupture? Does having a rear boot put more pressure on your lower ankle then a tow strap would? Would this have happened if I had been in a toe strap and not a rear boot? Or not?
