What possible reason could there be for shoe companies to ignore those of us who wear a 10.5 shoe? I'm disappointed when a shoe brand stops at a size 10, but I'll reluctantly accept it as a legitimate marketing decision.

I'm baffled, though, as to what could possibly be the reason for a company to exclude a size 10.5 when Its range goes to an 11. Makes about as much sense as offering every full and half size except a 7.5. Any ideas as to why a 10.5 seems to be the forgotten stepchild of the shoe industry?
