I have been searching for a great pair of shoes for my toddlers that wouldn't break the bank. Everything I had found previously was poor quality or my kids complained of discomfort. After receiving these my kids haven't taken them off. They are durable enough to ride bikes but lightweight enough for everyday use and water play. Perfect summer shoe!
