They are a little hard to put on, but once you get the hang of it, it's not a problem. These are not the best on a sandy waterfront though, the sand comes in through the holes and STAYS! FYI if your feet are sensitive, rocky terrain can get a little painful, as the bottoms are thin and flexible.
So dissapointed that these were giant (for a toddler) when they came in the mail. The medium are more for a small lady rather than a toddler. I don't think I will be shopping online here again. I am very unhappy!
