The shoes are really very large. My son has in shoes from Adidas size 28 (Adidas falls well known from small (as small size orientation, as popular children's shoes)), so I ordered him these shoes in 26/27 and they are still almost a thumb's width too large. Size 24/25 would probably have been more appropriate since the shoes really aware of just one bathing season will be used and a security intended to represent by fit. In big shoes to the risk is simply greater that the child falls. My son found it too uncomfortable to wear in the water, because it was through the air between toes and shoe shoe just too heavy to move. We keep this shoe just for next year :-).
Otherwise a really pretty shoe at a great price, I would buy my little treasure again
