I ordered the size of my son is 27-28 but they were much too big suddenly I had set aside for next year and had recommended size below thinking that the size would be more appropriate but this times- one, they were much too tight and I had to return to my great regret. It's amazing the difference between 2 sizes anyway. Otherwise I love this model, much less coarse than the original model. They are very convenient to put on, easy to maintain and very comfortable. Too bad my little piece can not enjoy it for the moment ... by this summer, I hope.
