Peeling skin on soles of feet

It's already been more than 15 days since she got over the Hand Foot and Mouth Disease but I still notice her toes and heel area skin peeling. I think what she has is small white-ish/clear colour blisters that eventually burst and peel. I don't see too many of these blisters though. Mostly all I see is peeled skin around her toes (soles). I feel nervous: I think she completely recovered from HFMD but is she still contagious? We've been playing at the Early Years Centre and the day care centre she will be attending starting September. Hopefully she's not contagious because I haven't kept socks on her feet due to the extremely hot weather in Toronto.
