I agree with other reviews about this shoe being small. I mostly get away with 12W but not with this. I've had to order 13(4E). Actually, the width wasn't too bad but I'll be on the safe side getting the 4E sizing along with one size bigger. Will edit this review when larger size arrives. Otherwise I think I'm happy with it.
Edit: Not the most comfortable shoe out there. I have put insoles into them which makes them a whole better. Otherwise OK.
