In 2014, when BOOST was still in its infancy, adidas were experimenting wildly with new contemporary designs in an attempt to find their footing in the coveted lifestyle market. From this era of experimentation emerged the SL Loop, a lightweight runner that stuck around little more than a year before fading into obscurity.
At the tail end of the SL Loop's lifespan, Extra Butter designed a velour-clad colab of the model's Racer iteration that was intended to release as part of their 2015 'Vanguard Collection.' The design was inspired by Wes Anderson's The Grand Budapest Hotel and its character Mr Gustave's membership to the Society of the Crossed Keys. In the spirit of society's exclusivity, only 100 pairs were scheduled for production and intended for a family and friends release.
Extra Butter art director Bernie Gross shared the unreleased sample with Sole Collector and explained its fate. 'Logistically, it was just in production and sampling really late.' Gross explained: 'As we all know with a lot of sneakers that have to do with anything copyrighting, it gets kind of hairy, so we decided to scrap it.' In fact, they scrapped it before even completing a single pair - only one left shoe exists.
Given the demise of the SL Loop, don't bet on this unreleased Extra Butter x adidas colab ever seeing the light of day (though, adi, if you're reading, we think it would work just fine on a BOOST sole... wink wink, nudge nudge!)
