Re-inventing the physics of kicking a football

The Concave boot is a revolution in athletic design. The boot contains the patented Concave Element, which is situated on the instep of the boot (or the ‘sweet spot’) – the point of optimum power and accuracy for kicking a football. The Concave Element naturally complements the convex shape of a football, creating a ‘cup’ for any football.

This design feature allows players to execute kicks with more accuracy, control and power on a far more consistent basis than with a standard football boot. Quantum widens the anatomical elements that make up the sweet spot and fuses these with a ball cupping shape, minimising the margin of error, and increasing power by up to 15% and accuracy by 40%.

The boots feature other innovative features including Metaguard- a protection system for the metatarsal bones of the foot and a concealed lacing system to further improve accuracy and control.

Cobalt are long time design partners of Concave – and assisted with product design and engineering of this revolutionary product right from initial idea to production release and the ongoing product optimisation and improvement.
