I have two other Star sneakers - both size 9.  I really, really wanted the Rose wash color and it was only available in 9 1/2.  I went ahead and ordered them, and I love them as much as the others - I just need to wear a sock so my heel doesn't slip.  I have a wide foot, and with a properly wide shoe wear an 8 1/2.  I am used to buying 1/2 size bigger just for a little extra width.
