I recently overshot a jump and the impact caused me to dislocate my ankle, break multiple bones, and tendons tore completely from the bones. Having surgery number 2 tomorrow. I was wearing basically brand new sidi crossfire srs boots. The doctors all have told me my ankle rolled to the side and buckled. I agree with them as the dislocation was nasty and definitely looked like a sideways shift and not a hyperextention like you would expect an ankle injury to be in that type of force. Anyway I know if you take a good impact to your head its time to retire that helmet, the foam is compromised it did its job. Is it the same with boots? It flexed in such a way to allow that much damage I know with lots of materials once you make it flex once like that it only gets easier after that. Any opinions?
