I am a women's size 5.5 and I had to buy the kids version of this shoe instead of a women's size because a size 6.0 was waaaay too big on me, and that's the smallest size they carry for women. I ended up ordering a size 3.0 in kids, and it still was too small! I had to return and buy a size 2.0. They fit a little snug, but now that I've worn them a few times they are more comfortable. A size 2.5 would've been perfect if they carried it.
