A limited edition Primeknit Pure Boost was released today at select consortium stores.  It is available in 2 colorways, either black or grey.  It features the full Boost sole combined with a knit material upper.  A few of the stores known to have it include Sneaker Politics, Sneakers N Stuff, as well as in store at Packer Shoes and Titolo.  It is selling out fast so this one will be hard to get.  The Primeknit Pure Boost is not likely to show up for sale on the main site any time soon.  The cost is upwards of $200 for this model and expect sizes to be in the 6.5-12.5 range as it is for the Pure Boost shoes.
