The Mavic Zxellium road shoes are designed for professional riders and is loaded with top-end features. It has a very thin 5.5mm full carbon sole to provide stiffness and a low 7mm stack height to be as close to the pedal spindle as possible for efficient power transfer. The carbon Energy Lock heel holder keeps the heel in place and is 50% lighter than molded heel cup. An energy frame surrounds the foot and assists force transfer. There is a textured section to keep the cleat from slipping as well as toe and heel pads to protect the sole when walking.
The Zxellium has three straps. One is a lightweight ratcheting design for exact tension. Two Ergo straps are adjustable to allow full contact with the Velcro pad and provide better airflow and ventilation. Comfort is provided by the Ergo fit system including elastomer inserts under the heel and metatarsal. The Zxellium road shoes have enjoyed a lot of popularity because all the features work to provide a light, stiff shoe that fits well and looks great.
