Respuesta de SkatePro: Thanks for letting us know that the sizing seems quite small! We will add this information to the website.
If the skates have not been used outside, you are naturally welcome to return them, and either get your money back or exchange them to another size.
Our returning policy is explained here: http://www.skatepro.fi/a73.htm
If you wish us to translate it to English, contact our customer service at firstname.lastname@example.org and we will be happy to help you.
