Hi there, my dd has hypotonia and hypermobility and has to wear piedro boots to keep her ankles stable. However, for one reason or another she hasn't been wearing them over the summer but yesterday she wore her new pair for the first time for about an hour and now has blisters on one of her heels. I'm not sure what to do - should I take her back to the hospital? Or is it because the boots are hard and need wearing in? I hate this whole feet / shoe thing - it is so difficult. Sorry if I've posted this in the wrong place.
