Slightly larger than other size 10's, but on the whole -- that's a good thing.  The top straps are rather long for my feet, but I solved this by putting small (sticky) Velcro tabs on the side of each shoe to keep the strap from sticking out.  The memory foam insoles make the shoes very, very comfortable.  Haven't had any problem(s) with wearing them all day & will probably be buying a second pair in black.
