These are not genuine leather or extemely nice, but for $13 (including shipping) they are cute little quick go-to shoes.

I am more of a 7-7.5 shoes size.  At the reccomendation I went to an 8, since everyone said they run small.  I actually wish I had not, since they are slightly big.  If you are a solid 7.5, then I might go up, but if you can also wear a 7, then the 8 will be a tad large.  Hope that helps.
