Building off the original S-Phyre platform, this second version of the SH-XC9 S-Phyre shoe continues the design legacy by adding refinement with improved ventilation and new insoles. This pure performance shoe was designed as a whole, meaning the upper and sole were created at the same time for complete fusion and synergy.

The S-Phyre story starts with the Teijin Avail synthetic upper. This magical Teijin material is extremely supple and smoothly wraps around the curvature of your foot, while offering maximum support. The upper's sides are guided together in the Surround (no tongue) method for less seams and volume reduction. The back of the upper has a rather large one-piece molded external heel cup which does a good job of wrapping your heel and providing stability. The micro adjustable and dual independent Boa IP1 dial/wire closure delivers incredible fit and are strategically placed to asymmetric Powerzone wire anchor locations for performance optimization.

At the core of the SH-XC9 S-Phyre resides the stiff, lightweight and surprisingly thin Dynalast carbon fiber sole. This refined sole design features anatomical curvature to serve up proper foot support. It has a unique toe lift position (called toe-spring) that increases leveraged power with less strain forward of the metatarsal zone. The seamless mid-sole construction process eliminates the board last, which reduces both weight and stack height. Michelin compound rubber was sourced for the tread to provide the final word in surefooted grip in any conditions. The rear 3/4 of the sole are wrapped in thin high durameter rubber to add extra protection to the sole and improve grip on loose and uneven terrain.
