I wear the 39 Reg in sandals and the 40 Reg in shoes. I gots double-wide feet, to I need sandals with the buckles that can be adjusted or shoes that I know have some give across the instep. I'd love a pair of clogs with a raised heel like the Alton, but I just don't know if it would be too narrow for my tooties! I guess I'll just have to order some and try them on, or see if there's a store nearby that carries them. A friend told me about a Birki Outlet about an hour away. Maybe someday I'll get down there to check it out!
