Adidas continues to grow the Ultra Boost Uncaged library with yet another colorway set to release later this year. Seen here is the Uncaged Wool version of the Ultra Boost Uncaged sporting a black/grey colorway alongside a matching boost. Grey / Black laces tie these up, matching up with the PK upper. Lastly, a glossy heel cup is added on the heel with Ultra Boost branding. Look out for these to release at adidas running retailers across the globe later this year.
