You're like a year late dude, those are from f/w 2013. Best bet is to check with your local dior homme or the one in nyc and ask them, but my guess is that unless they pop up on ebay you're out of luck.
My Nyco Freeshell came today. I'm keeping it although I agree that the cuffs are a little bulky. The Nyco is placed in a way that it's lack of stretch doesn't restrict my movement, and I think it creates a nice visual effect.
