The black-out Adidas X 15.1 Prototype Boots feature a low Dynamic Fit collar for a flexible ankle support. Adidas combines the thin synthetic upper with an external cage for more stability. Interestingly, Ángel di María's latest prototype boot features a much thinner external cage than the leaked blackout Adidas X 15.1 Boot.

On the tongue of the blackout Adidas X 15.1 Angel di Maria Boots is a brand new crossed 'X' logo. The X is expected to be the logo of the totally new Adidas X 15.1 Boots.

Manchester United midfielder Ángel di María becomes the latest player to train in the totally new Adidas X 15.1 Prototype Soccer Cleats. In the last few weeks, various high-profile Adidas players have been training in new blackout Adidas 2015 Prototype Football Boots, which are set to be officially launched in June 2015.

Phil Jones also laced up in new black-out Adidas 2015 Prototype Boots. Phil Jones' blackout Adidas 2015 Prototype Soccer Boots are the same used by players such as Iker Casillas and Mesut Özil, and are reported to be Adidas' new control boot.

Adidas will discontinue the Adipure, Adizero, Nitrocharge and Predator Boots from Summer 2015. Check out all upcoming Adidas Football Boots in our Boot Calendar and the leaked yellow Adidas X 15.1 boots.
