I measure in between a 9 and a 9.5 in length and just about a D width. I tried on the Delray in 9.5D and the heel is loose (I can fit an index finger between my heel and the shoe). I tried on the 9D and the heel is just slightly loose(I can fit my index finger about 1/4 in), but I say it's pretty good, but the width around my toe area could probably use a little more room. I'm not sure if Nordstroms usually carries an E width, but would going to a 9E fix the problem or would it be better to go to a 9.5D. The 9.5D feels fine except for the loose heel, my heel doesn't come out when I'm walking though. I don't know if going to a bigger width on the size 9 would make the shoe feel loose all around.
