In reply to abr1966:
I've tried Sidi, but found they're the wrong shape for my feet
Being Italian, they come up quite narrow and, I think, small for the stated size. They do a wide fitting in some styles, though, called the Mega.

Try lots, though - I've got a pair of Diadora ones that are SO comfortable (and kicking myself that I didn't keep a second pair in a different colour). However, a different style didn't fit me at all!
