Well, you had Dragons before? You will know they changed the heel and material around the laces, along with the sizing slightly....
Therefore these are probably the equivalent to a new style 7.5....hence why they are a little too small for me.....however the heel is better in these (old style) which is slightly annoying.....
Let me know, I take a 7 in Whites/7 in velcros and by normal shoe size is a 9
