I have a pair of Sorel boots, size 11 american, and they are HUGE!!!! I bought them a little larger, so I thought, because I normally wear a 10 or 10.5 depending on the brand. I didn't want them too tight, and I wanted to wear heavy, thick socks with them, so I thought an 11 would be ok. OMG.... I wish I could send them back, but I got them last season, and it's too late now. They are very comfy, and very warm, but gosh are they large. This is the price you pay when you order online and don't go in to try them on.


I think the 11 is a 42 or 43?? What ever it is, it is huge.

I found this chart however, which does conversions for shoe sizes.

ETA: I also bought Dave a pair of Sorel last year so he has warm boots for outside. He wears a size 12/13 mens (depending on the brand, some fit smaller than others), and his Sorel's are a size 12 and are a generous fit, he says.
