Bayern Munich's Thomas Müller continues to wear a blacked-out adidas Prototype ahead of a suspected silo shake up coming out of adidas HQ in 2015.

Müller had already sported a version of the boot in September as he works closely with adidas to supply feedback on their next adventure. The blacked-out boots he's wearing here are thought to be a next-stage prototype, improved on the previous version, as adidas begin to head towards a final edition of the all new silo.

Some description

The most distinctive feature on the German's mystery boots is the new material surrounding the topline are of the boot, a sock-like material that extends up the ankle. A familiar design that has of course been seen already this year and could spark another clash between adidas and their certain Swooshed rivals.

Some description

The unrevealed boot, along with another unknown silo seen on the feet of Iker Casillas and Xabi Alonso, could well see one of the the most dramatic shifts in direction for the adidas boot line-up for a long time and will pick up serious pace at the turn of the year.
