oooo, so now you're looking at Sidi's?

Go to the LBS and try them on, you don't have to buy them there.
Mine are the lowest end model called "Blaze" and I got a deal for a hundred bucks. I like them a lot and I think I have wide feet.
They're made of a material they call Lorica but who are they kidding, it's plastic but it's breathable. I doubt it will stretch.
Did you get your pedals yet?
