A patented sole element that gives the sole exceptional resilience and helps translate the energy stored during landing into a dynamic rebound. It is used in the Road-X series of shoes. It consists of several nylon rods arranged along the sole, which flex during the first phase of the stride and store energy. When the foot rolls onto the toes, the bars act like springs.

The new midsole provides significantly improved rebound and energy return, while also being more durable and retaining its shape for longer. Thanks to this construction, the shoe gains longevity while improving comfort and energy transmission.

The grooves in the midsole and outsole with META-FLEX technology provide multi-directional flexibility underfoot for reactive movement in every direction and traction on the terrain. In addition, they remove water from the tread very quickly.

The outsole of the Inov-8 brand shoes, it is made from a specialised rubber compound that provides excellent grip on a variety of surfaces. The sole also features an aggressive tread. All this results in confidence when traversing demanding terrain.
