Joybees are made from EVA materials, which will shrink if exposed to extreme heat. We advise keeping your shoes out of direct sunlight and excessively heated environments. Your Joybees won't shrink while you're wearing them, but don't leave them in a hot car on a summer day.

EVA can also shrink if subjected to prolonged water exposure. While they're fine to wear by the pool, don't leave your shoes in the water for an extended period.
