NYC has a number of upscale/hip sneaker stores that may or may not have what your looking for. One that comes to mind is Alife Rivington Club - they have a number of limited edition and imported sneakers (2 stores in NYC). Barneys is also worth a try.
Thanks for the stores, I will check them out. Other stores I found (not all of them carry Puma): NEW YORK Adidas Originals 136 Wooster Street +1 (212) 777-2001 Head Porter +1 (212) 995 8108 Nort 235 235 Eldridge Street, Lower East Side Prohibit 269 Elizabeth Street, Elizabeth & Houston Supreme 274 Lafayette Street +1 (212) 966-7799 Stussy 140 Wooster Street +1 (212) 995-8787 Jon.
