Sizing - fit 7.5 Women, it’s US Men 5.5 but they do run a little bit large. They are big for me, I wear 7 Women. Worn. Leather! The 424 x Superstar Shell Toe 'White Scarlet' released as part of a collaboration with the Los Angeles streetwear brand. Built with full-grain white leather and off-white on the heel patch, the 424-branded tongue tag adds color in scarlet.
