Friendly Fit: A little extra room with a secure feel. Quick-clean, water-friendly sandals that hold up for the bravest explorers. The Adventure Sandal rinses right off and is ready for the park or next big backyard adventure. Watch out for the sun! Joybees are made of EVA, which will shrink if exposed to heat. We advise keeping your shoes out of direct sunlight and excessive heat. They won&';t shrink while you&';re wearing them, but don&';t leave them on the front seat of a hot car while at soccer practice. After a long day of play, rinse clean with cool, soapy water and a gentle scrub.
