Mercurial XI is the most advanced boot technology wise, ever produced by Nike. By combining science with design, Nike has managed to develop a boot where all components work together with one purpose: to allow the player to reach his full potential. The boots are lighter and stronger than ever before, backed by science and designed to work together with the foot. This is the science of speed, this is speed redefined!
Teijin upper packed with innovative details
Vapor XI is designed with an upper made from Teijin, an extremely thin and flexible material allowing for an almost barefoot feel and touch on the ball. The upper has been given raised horizontal grooves, to increase the level of friction between the boot and the football. This way your attention and interaction with the boots is heightened. You get an improved touch on the ball and a closer, more precise and natural touch when dribbling, passing or shooting in high speed. The front part of the boot, has been designed with a low profile to allow you to get under the ball for even better shots and passes. The upper has been coated with the All Conditions Control (ACC), for excellent touch on the ball in all weather conditions.
Integrated tongue for better lockdown
The tongue is integrated in the boot, working with the frame of the boot. When you tie the laces, the design shapes to your feet and ensures that your feet is pushed down on the sole. This allows for the ultimate lockdown, which is needed at high speed and sharp turns – also adding to the responsiveness of the boot.
Groundbreaking way of thinking is the foundation for a unique outsole
A conventional way of thinking, when talking about outsoles for a pair of football boots, has been flat form. But Nike realised that the problem was, that people’s feet was anything else but flat. As a logical consequence of this, Nike started working on the development of a new outsole plate, which follows the foots anatomy. The result became a curved and light nylon outsole, which consists of a single layer chassis, that is 40% lighter, stronger and more responsive than the carbon sole on the Superfly IV. By having an anatomic outsole which follows the foot, it reduces the gap, which existed on the carbon sole, and offers a more natural fit. On the front foot the sole has a Split-Toe function, which increases the foot’s flexibility in the boots, so you get an improved grip on the pitch.
Stud system designed for acceleration and deceleration
In the modern version of this beautiful game, much can be decided, if you can run and change directions quickly. An essential aspect in this, is that you can achieve a high speed within short time. A thing which is equally important but often forgotten, is if you can stop quickly enough. Nike has designed a completely new stud system with help from an advanced computer system. Pressure points and the flow of power was mapped. So was different forms, patterns and compositions – all being thoroughly analyzed. Nike found the ideal combination, and the studs were placed at different place where grip was needed the most. The studs are angled so they work as claws during acceleration and quick turns. They work equally effective when decelerating, which makes it easy for you to stop and change direction when you want.
