Last week Kim Kardashian-West debuted a brand new Adidas Yeezy Boost 750, which was later followed by leaked images of a never before seen Adidas Yeezy Boost 650.

Today, we have another mysterious Yeezy Boost on our hands (courtesy of @BaltSneakerShow), one that looks similar to the Yeezy Boost 350 but features a very subtle change.

Die hard sneakerheads will notice that the Boost sole which is typically covered by a chunky ribbed shell, is fully exposed on this pair of kicks. The full length, visible, bubbly textured sole is reminiscent of the wildly popular Adidas Ultra Boost and should provide for more comfort.

The sole still features the grooves that have become synonymous with the Adidas Yeezy Boost line but the faint update to an exposed Boost sole is something that some fastidious sneakerheads will either love or hate. I'm indifferent on the matter- they look the same IMHO.

There's no word on whether these Yeezy Boosts are ever coming to retail or if they're merely a sample pair but it'll be interesting to see what Kanye and Adidas cook up next.
