Following yesterday's eventful release of the "Moonrock" Yeezy Boost 350, adidas continues proving to be the most popular brand in footwear. The sportswear giant's surge to relevancy is primarily a result of two factors – boost technology and Kanye West. Both factors come together in the form of an exclusive new colorway of the adidas Ultra Boost, an already widely popular silhouette.

West's personal barber Ibn Jasper took to Instagram to preview a new Friends and Family adidas Ultra Boost. The sneaker features a heather grey and cream colorway, which looks somewhat like a mix of the "Grey" and  "Triple White" Ultra Boosts. Jasper stunted by using the hastags #YouCantBuyThese and #NotForSale, but a search on Grailed shows a pair for $700.

For nearly as much as Yeezy Boost 350s resell for, buying an either the "Grey or "Triple White" Ultra Boosts might be a more realistic option. While there's no sign of a retail release to follow, stay posted for any additional information.
