My little daughter has been dancing for 2 years now and these are the only ones I buy for her.  We have tried other ones, but these seem to have the best fit.  The straps have to be sewn to size, which helps create a snug fit. She also loves them because the straps cross in front, making them look like toe shoes.  They are also washable.  One word of caution, they run a little snug.  I recommend actually getting a whole size (not half) larger.
