My son is a US size 2. His current Evolv Venga, also a US size 2, is too small for his foot. He doesn't even fit in a shoe. I took a chance and ordered them a US size 3 and they fit him perfectly. There's even a little bit to grow. In short, about 1 size larger than your current shoe size should work. I would give them 5 stars but the quality isn't really great, a lot of extra glue on the shoes and mismatched soles. Otherwise they are fine and he likes them.
