Had to go up half a size. They look great and return was easy.

I have needed a new pair of NB 623's for some time now, and I have been hesitating strictly because of some of the recent negative reviews. Finally, one of my laces gave out, so I decided to suck it up and give these a try. I have to say I am impressed with the look, the fit and the comfort! Usually I dread getting a new pair of shoes because I can only wear them for 2 or 3 hours at a time until they break in. With these, I was able to put them on, go for my daily walk, and continue wearing them as long as I pleased.

I don't know the version of my old pair, but I know I have had the old pair for at least 3 years (as I bought 2 pair at the time), but one identifier of the older pair was the "623" is in an oval on the heel (white numbers on a navy background) -if this helps any aficionados do a comparison. Whatever the case, I am impressed enough to order at least one more pair to set aside for later.

These fit as expected - can't lose them ein this colour either!
