Im an off the charts 8 4E+ and Ive now given up on these skates.
My custom skate size is about a 7.75 EEEE in a custom bauer, I also have a very flat foot with almost no arch
The shop had me try a size 8 as well as a size 9, went with the 8 since the 9 felt loose front to back even without baking.
Ive had my skates baked a couple times but I just cant get rid of foot pain on my arch/side of foot. Just cant get the size 8 boot wide enough to fit my hobbit feet. I love the ankle flex these provide but have gone back to my custom bauers/Trues and now appreciate how comfortable they are
