There's been talk about sizing for this a while back in this thread. Just search for Hikers or 240. I have a pair in size 10 which fits fine. My second pair of vibergs also in size 10 will be on the 2030 last but those are due probably end of next week or the week after so I can't compare right now. For reference I'm a 10.5E (wide) in Allen Edmonds number 5 last (Park Avenue, Strand, Cambridge).
