They have backings including in the packaging but they arent attached to the earrings. But these! Very happy with my choice . They are very slippery, and your foot slides forward in the shoe easily. I need a 13 in the Duet Sport. Very much needed I have a lot of purses and accessories. ) If you press down too hard (say, by accident) on this dock when its connected to the laptop you will more than likely do some serious damage to the dock and/or MacBook Pro. myself but at this price - not worth it to DIY! What kind of crap is this??? Dont waste your money! They arent the "typical cute shoe" of course but the comfort makes up for the fashion any day of the week!
