I got this shoe for my 10 year old, who wears a size 4 in Tom's. We originally ordered a youth size 4, but she does not like the new thicker, softer sole (it's not cool, I think). So we looked on the Tom's website to see what size in Women's corresponded with a 4 in youth and the site very clearly says go up two sizes to convert from kids to women's. But the size 6 we ordered was CLEARLY too big. So they are just wrong. We are sending them back to get a 5 1/2. I would give the shoe a 5, but the size conversion should be accurate, so I'm a little annoyed. Great shoe though.
