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).

The small print
What we commit to is dispatch, not delivery. If your order meets the cutoff above, we pack it and hand it to the courier on time. That part is ours and we hold ourselves to it.
The delivery leg belongs to J&T Express or SPX. Once a parcel is scanned in at their collection point it is in their network, and their collection and delivery schedules are not something we control. Missed collections, driver or route changes and courier system outages do happen, and when they do a next-day parcel can arrive a day or more later than this page suggests.
What we do about it. Every order gets a tracking link the moment it is scanned in, so you can see exactly where it sits. If a collection is missed or tracking stops moving, email admin@inlinex.com.sg and we will chase the courier directly rather than leaving you to do it.
Next-day delivery is a service level we aim at and hit on the large majority of orders. It is not a guarantee, and we would rather say so here than have you find out from a late parcel.
