DD recently moved to a new gym (September) and has commented from the beginning that she finds the floor very hard. She's getting more rebound, but recently has been complaining of ankle pain. She uses supports for her wrists; I was wondering if there are comparable supports for feet/ankles other than just wrapping. Would a heel cup like used for Sever's work? Anything else you know of would be much appreciated - she has problems with overuse injuries in general and I am not eager to see another one develop.
