Good question. Never thought about it before but why are there women's and men's specific running shoes?

My local running store carries men's and women's, so they don't seem to be unisex.

I got a pair of womens carbon x from my local running store light blue same color as mens funny thing it was 8.5 womens and im mens size 7.5 usually 1.5 dif also the width was fine usually womens run b and mens d width. I have had wide variances on hoka claytons also. Best is to try on individually which is so hard when your below a mens 8

In some models, are W is normally narrower and sometimes less cushioned.

Still puzzled :-)

I beleive the carbonx is one full size smaller for mens and width depends on cut or luck or both

Right. Sounds like W is a no go in this case. Thanks a lot
