I have plantar fasciitis (which causes heel pain with every step) and decided to check out this brand, which has a reputation for providing good fit and comfort.  I saw this product listing and decided to try the New Balance WW759 shoes in the blue/grey.

I had never tried on New Balance shoes before, so I ordered the two most usual shoe sizes for me (the smaller of the two was my typical size and the larger of the two was a half size up from that), knowing that I could count on Amazon's great shoe return policy for the pair that didn't fit.

Sadly, neither pair fit my feet.  Even the larger of the two shoe sizes was too small length-wise - so I would have had to go up one further half-size, at least, for this shoe to be long enough for my foot.  Unfortunately, both of the pairs I got were too big in the heel, so going up another half-size would make the fit in the heel even worse.

Due to the poor fit, it was clear that I'd have to send both sizes of the 759 style back, and try a different model of New Balance shoes, or a different brand altogether.

Positives of the WW759:
-The base of the shoe did feel very comfortable and supportive in terms of my heel pain / plantar fasciitis.
-The shoe seemed well-made.
-It looked like the photo in the listing.

Because I was surprised that the heel fit me so poorly, I had a look on the New Balance website for further information on how their shoes are sized.  Oddly, I had to dig around quite a bit in their FAQ section to find useful information on this.

To make their shoes, they use several different kinds of lasts (shoe forms/bases), and these vary along 4 dimensions - the fit at the heel, the fit at the instep, the fit at the toe box, and the fit at the forefoot.

**NOTE:  This WW759 shoe is listed as having an AL-2 last, which offers a standard heel size, a higher instep, a deeper toebox, and a standard forefoot.**

On their website, you can select what sort of shape your foot has, and what sort of fit you are interested in, and see which styles match it.

In a comment attached to this review, I will post the best internet links I could find about New Balance's sizing and shoe last information.  I hope this might help some folks as they are shopping online for New Balance shoes.
