That's fantastic information, thank you so much. I also have a Play-It-Again near me, maybe I'll go there first.
Your last statement brings me to a new question. I am also a bigger guy (about 280) and my feet are always killing me after about 10 minutes of skating. I wouldn't mind paying for a little more comfort for myself. What skates do you use?
Probably the thing that's going to make your feet hurt less after a while, is just training your feet to the rigors of ice skating though. There's really no such thing as a "comfy" ice skate imo. At least, not a hockey skate. For full authority over your edges, you kinda want it to be a little bit uncomfortable.
I mean, if you're just sticking your foot into a skate and it's immediately uncomfortable...obviously that's bad. But there is a point where even a perfectly comfy skate while just sitting there, should probably become a little bit uncomfortable at some point while using it. You're exerting (however much you weigh) pressures through one part of your foot at times. It's aggressive, and not always comfy.
To switch to a more relevant gear...the more you learn to comfortably use your edges, the easier it'll come to you, and the less it'll hurt your feet. But still...the stiffer the skate, the more it's going to "feel bad" if you're not used to it.
Could be that you have really wide feet and there are skates for that, or maybe you just have skates that aren't the right shape...like @FilthyDangles posted above But also as per that chart...what sort of foot shape do you have? It's *super* important to skates fitting well.
