Go for it like never before

It has an additional 20% of the famous Boost compared to its acolytes is a midsole Boost 100%. It brings you incredible energy return and amazing cushioning every moment. You adopt an ultra smooth stride throughout your running workout.

The Torsion System is revisited to gain stability and ensure a more efficient and in-line foot roll. You are more dynamic and fast!

 

For the bodywork, it's knitting

Because the comfort of your run does not stop there, the PrimeKnit fully knitted slipper offers you an ideal fit. In one piece, it slips on like a sock, for a second skin effect, with the help of the back tongue.

 

Agile and lively, a racing car is approaching

The miles pass under the Stretch Web outsole without any inconvenience. It matches the movements of your foot at every step of your stride. Its Continental rubber promotes increased grip and improved wear resistance. The crampons offer great flexibility to the sole while being safe on a wet road.
