I just tried to add the black Flotros off Footlocker, getting the same error message. Either their out of stock, or listed early in error. Either way, the fact they are at Footlocker hopefully means they'll be an easy cop come the 22nd.
Picked up the Pinks early off ebay right before finals. The color is so much nicer in person. As a wide footer with short toes, these fit me perfect, about the same as the Curry 9's. Others might need to go half size up if you don't want a 1:1 fit. Just compared them to the original Curry 4s and they fit about the same BUT so much more comfy. Best Currys ever, and its not even close.
