They are very light and my 4 year old son seems comfortable in them. And Little Kid 11 is perfect for him. He usually wears Adidas or Nike and has recently outgrown size 10 Adidas water boots (he can still wear size 10 regular Adidas/Nike sneakers. Their water shoes are slightly smaller). As every brand has a very different fit I wasn't sure if the Little Kid 11 would be the best choice but it fits him perfectly. Hope this helps someone!
