The never-before-seen Yeezy looks continue.

After showing several unreleased pastel Yeezy Boost 350 V2 colorways and a new Yeezy basketball shoe, Kanye West has shared what he's calling a Yeezy 451 early prototype.

The shoe strays from the knit runners and bulky retro-inspired designs that have largely made up his Adidas output thus far. Instead, the 451 veers more toward a minimal hiking shoe upper with the addition of a molded midsole design that wraps the sides of the mesh-based sneaker. 

Like the rest of Kanye's recent shares, there's no word when—or if—this model will release at retail.

UPDATE (08/20): Kanye West shared an update on the design process for the Yeezy 451 on Twitter. It gives a closer look at the traction pattern being worked on by notable sneaker designer Steven Smith. The Yeezy 451 is expected to debut at retail in 2019.
