With a design and construction with the single aim of producing the most power efficient shoe possible, Northwave looked into every aspect of the shoe, from how the sole is constructed to how the retention system affects power transfer. Carbon construction methods were tried and tested to find the ultimate level of stiffness and efficiency. Numerous versions of the dial retention system and dial placement were tested to find the balance of security, comfort and power transfer. The heel design refined to prevent any heel slip and the footbed optimised for power transfer.
PowerShape Carbon 15 sole
Constructed from 100% unidirectional carbon fibre, the PowerShape Carbon 15 sole featuring the exclusive Powershape® system on the arch of the foot delivers 100% power transfer from you to the bike. No watts are wasted as your power is channelled through the shoe to the pedals. With a stiffness index of 15, the Extreme Pro Road Shoes are the new performance benchmark for road soles.
XFrame 2® upper construction
The ruthlessly efficient design of the sole is further enhanced by the use of the XFrame 2® upper construction. Giving a super secure and snug fit without any uncomfortable pressure points while ensuring transfer of power.
Double SLW2 dial closure
Comfort and fit are enhanced by the double SLW2 dial. This differentiates the pressure between the top of the instep and the toe for even better adaptability and even distribution of pressure.
Integrated heel system
An integrated heel system containing directional fibre prevents slipping and improves comfort.
Pro Regular Fit footbed
Power transfer is further increased by the Pro Regular Fit footbed with a stiffened dual-density design.
The shoes are compatible with 3 bolt fitting cleat designs, and also work with the NW Speedplay adapter for the lowest stack height between foot and pedal. This ensures that foot placement is optimised for maximum power transfer. The only shoe choice for the serious racer seeking every performance benefit they can.
