Pretty sure my foot size is weird... The 7s are way to small. I have the old black and white checkered in 7; however, Im more of an 8 in most sizes. I ended up donating them, but i went with the 71/2 on the second try. I can get my foot in now but theres space at the heel. I know i had to break in the black and white ones.. but that was 5 years ago.. 1/2 size seems to be a whole size
