Adidas is being slick by releasing their ever so popular Ultra Boost runner randomly at three stripe stockists across the globe.

The latest to make it’s way secretly into retailers is this Dark Grey colorway that released over at Renarts. The Ultra Boost features a grey colorway on the uppers and with it’s signature white ultra boost outsole. Tonal greys make up the colorway on this limited release, with a lighter grey on the collar. These sold out but stay tuned with Modern Notoriety for a wider release.
