I'm running 68k's. So far I've skated 3 times during stick and puck and baked them twice (once before my first skate and once before the last).
I can definitely understand when people say they're comfortable, but I have a wide mid foot, specifically on the outside, and they're killing me. Considering I only have 3 skates on them, I'm not really worried yet, but I'm fearing that they're just cut to narrow in the mid-section for me. I have 8.5EE and I normally run 10s or 10.5 in shoes.
I'm coming from CCM U4s size 8.5D, and I thought they were narrow. But when I compare stock insoles, the ribcors are narrower.
I'm going to start wearing them around the house with thick socks, but again, I think I'm kind of limited on the amount of room the boot will give from the mid foot. We'll see...
