I just spent two hours of my life tracking these down in a size 5.5. Of course I bought these in the Royal Purple color! They're back ordered from Nordstrom until the 22nd but I'll accept that considering these sold out in minutes! I'm crossing my fingers these aren't cancelled on me. Puma's website is almost completely sold out in every color and size.
They also come in Black and Glacial Gray
But the velvet Royal Purple is definitely the best color.
Buy them here-
Bloomingdales (has all color right now!)
