They stay pretty narrow, based on a very bad sketch attempt they are roughly 30cm long and 10.5cm at the widest point. Relatively high arches, I’ve got superfeet in my Jetspeeds which I like. My previous skates were size 12 Supreme total one’s which I hated, the Jetspeeds feel comfy so I’m chasing a similar fit. The only physical hockey store in my country only stocks Bauer and they never carry large sizes so I feel like the safest option is to stick with Jetspeeds.
