The Women's Retro Runner comes mostly in whole sizes (just one half size for women: 9.5) and, because they're converted from European sizes, the women's version of this shoe is really just an extension of the men's sizes and vice versa.
The foam insole is removeable! Which means that you can get a custom fit by replacing the insole with one that you've purchased to custom fit your foot (or add arch support or use orthotics, etc.) or just wear them as is.
ABOUT SUEDE SOLES:
We find that these run true to size. So order your usual women's dress shoe size. If you're a half size it's best to go up to a half size larger than usual (6.5 fits a 7, 8.5 fits a 9, etc.).
If your feet are larger than Women's size 11, just wear our Men's variety (they're really just unisex). Just subtract 1.5 from your size to get the men's equivalent (Men's 8.5 = Women's 10).
