Iker Casillas laced up in new black-out Adidas 2015 Prototype Cleats during today's Real Madrid training session, and he also wore brand new goalkeeper gloves. The new blackout Adidas 2015 Prototype Cleats are reported to be a totally new Adidas boot silo, scheduled to be released in Summer 2015.

The pictures of Iker Casillas' black-out Adidas Prototype Boots show a synthetic upper with a remarkable honeycomb structure in the forefoot area. The honeycomb pattern on the upper of the Adidas 2015 Prototype Cleats is expected to offer a better ball control in any conditions.

Xabi Alonso was already spotted wearing a similar black-out Adidas Prototype Boot in September 2014. In contrast to Gareth Bale's Prototype Boots, the Adidas Prototype Boots worn by Xabi Alonso and Iker Casillas feature a low-cut design with a traditional Three Stripes positioning on the outstep and instep.

Both Iker Casillas and Xabi Alonso are usually wearing Adidas Predator Boots. The new black-out Adidas 2015 Prototype Cleats are rumored to replace the iconic Adidas Predator Boots after more than 20 years.

Adidas Football will be going through a crucial period from this summer, after Nike launched the extremely popular Nike Magista Obra and Nike Mercurial Superfly Boots ahead of the 2014 World Cup. Stay tuned for more info about Adidas Football's biggest change in the last decade.
