I have these in the black, the orange and the hot pink and they are fabulous.  The shoes FIT TRUE TO SIZE,are classy, comfortable, and very well made.  The platform gives you great height but at the same time make the heel shorter than it looks.  If you can wear platforms and want something for work or jeans these shoes offer those qualities.  In terms of width, they are the regular M.  Any reviewer who claims they are too narrow likely has wide feet and should nto be purchasing shoes made for medium width (it's the reason why they make shoes in varying widths).  If you are looking for a pair of heels that work not only from casual to office dress but which also look sexy then these are it!  Happy shoe-pping!
