Hey! No, those are childrens, see in the title it says C8, that stands for CHILD 8, remember I said that Maddox wore a 9 but they ran big, so that is the size I got him, like a Child's 9, but it says child's 8. I just noticed that the seller does'nt have the child's size chart on that page, but you can google the Euro size chart. You would need to look under your daughter's (or your) Euro size. You can Google "Euro shoe conversion chart" and find out what your size is and then go to this seller's Ebay store and just type in that particular size. I'm not real sure about how they are when they're wet, I've never let Maddox get his wet and I don't have Birkenstocks for myself. If he does go in the water, he wears Keens brand sandals, these can be found at Piperlime.com and that's what Maddox will be wearing to Blizzard Beach because they completly cover the toes and have really good grips on them. HTH! Thanks, April
