Is that 10.5 to 11 in regular adult men's sizes, or is that a kid's size of some sort? I know my middle school daughter's shoe sizes confuse the heck out of me. Right now I'm wearing some Nikes that don't have any tags, but my Doc Martens are a 7 in US men's size. I don't actually think the shoes you have would fit me in any conversion I can think of.
I don't wear skinny jeans or anything with large logos or pictures of people or characters, but I wear flannels and t shirts and button ups. I don't mind stains, usually. If they're ugly enough I can put a patch over them and treat it like a hole. I need a belt.
I'm 5'7" and I weigh 125, if that helps. Can I be in line? I'm not sure that anything you have would fit me or be otherwise suitable, but I'm interested.
