Weighing a slender 240 grams, Mavic's Cosmic Ultimate II Wide Cycling Shoes feature an ultra-light design that doesn't compromise rigidity or comfort for wide-footed riders. The incredible efficiency of the Cosmic Ultimate II shoes comes courtesy of the Energy Full Carbon SLR sole, which boasts a 100/100 on Mavic's energy transfer index. The Cosmic Ultimate II also includes Energy Frame Carbon weave and Energy Lock Carbon heel counter to provide a secure and precise fit, ensuring you get the most power out of every pedal-stroke. Mavic uses a thin bonded construction for the upper to keep things light and breathable. The Ergo 3D tongue offers added ventilation plus a comfortable cushioning, and the ergonomic Ergo 3D + Ortholite footbed provides soft, stable arch support. To dial the fit, Mavic includes two Ergo Dials which allow you to make precise adjustments quickly and easily.
