These are excellent inline skates, perfect even for people with wide feet. I had a hard time finding the right size, so here are some of my findings and measurements in case it may help someone. This is still subjective in some respects, so please take it with a grain of salt. - Don’t rely on your street shoe size; measure your longest foot in cm (Mondo size) and check Seba CJ2 Prime's official size chart on their website. - Different sizes share the same shell. EU size 39 corresponds to the same shell as size 40, and the same goes for sizes 41–42, 43–44, etc. If between two shell sizes, if the smallest fits, take this one. - Liner will expend half to a full EU size (you should be snug/tight at first). - Try on the boot barefoot without the liner, with your longest foot, no socks. Touch the inside front of the shell with your longest toe and measure the gap between your heel and the back of the shell: a gap of less than 1 finger indicates a very tight “pro” fit; 1 to 1.5 finger indicates a tight and precise fit but still comfortable after a few sessions ; between 1.5 and 2.5 is comfort fit from the get go but it might become loose after some time (heel lift, sliding foot) ; more than 2.5 is definitly too big in my opinion. - In my case, choosing the smaller shell wasn’t possible, even though my foot is 25.9 cm long (I wear EU 42 street shoes) and size 40 skates should have been perfect according to the Seba size chart. It was definitly too small. Because of the width of my foot (10.5 cm) and the shape of my forefoot (the “Greek” type), size 41 EU fits me very well (pretty tight at first, snug and comfortable after a few sessions).
