The truth is, you just don't know how a shoe will fit your foot until you try it on in person!  That said, we do everything we can to include fit information in our product listings.  We try on as many models as we can, we read reviews, we pay attention when customers try the shoes on in our stores.  We'll include recommendations about sizing up or down in the product listing.  No two feet are exactly alike though, which means two people with the same size foot might not like the same fit.  Your foot's width and volume, even the shape of your toes might affect exactly how a shoes feels.Keep in mind that shoes from the same brand do not always fit the same.  One style from Sorel might fit smaller than another Sorel style, for example.  If a brand makes a new version of an old favorite, that style may also vary in fit.
