I wonder if adidas thought the Primknit collection would perform as well as it has? Now they are going for the niche market of limited edition with the latest adidas Primeknit Pure Boost Solar Blue shoe. This stunning blue shoe features the super lightweight upper and their strong gripy sole, along with other features that the Primeknit line has become known for. The shoe is a limited edition run though, so it looks like just 600 are being made! Set your calendars and watch the countdown clock!
