It's the morning of your target event. Your preparation has included a series of prep races and extends all the way back to the previous winter when a distant calendar date and an early registration race fee on your bank statement kept you from dipping into the pie and digestif cocktails after a holiday dinner. You've done everything you could to ensure that your body is ready, so don't take a chance on your gear. The Mavic men's Cosmic Ultimate Tri Shoes are the lightest, stiffest, most efficient shoes in the French firm's footwear stable, so they ensure that the only thing that can hold you back on race day is your own personal self. The barely there uppers consist of Ergo Bonded mesh and synthetic microfiber, which is designed to keep cooling ventilation up and weight and drag down. They're mated to the Energy Full Carbon SLR outsole, which is the same model used on Mavic's top tier road racing shoe. Compared to the nylon and fiberglass outsole of Mavic's other triathlon shoe, the Cosmic Ultimate's carbon sole is lighter, stiffer, and allows for more ventilation due to carbon's inherently stronger structure. During transition, the large, horizontally oriented heel loop helps you slip the shoe on while pedaling out of the gate, and the single Ergo Tri Strap secures in moments so you can focus on achieving cruising speed as soon as possible. The strap is also cut able, allowing you to eliminate any excess material while achieving the ideal fit for your foot shape. While on the road, the carbon heel counter reinforces the minimalistic upper to keep the heel locked in place, and the dual density Ergo Fit 3D Ortholite inserts provide targeted arch and metatarsal support to ensure a comfortable race at least until you hit T2.
