The Mavic Cosmic Ultimate Tri Shoe was developed to meet the needs of professional triathletes, designed to save time during transitions while transferring every last watt that's generated. Mavic had two things in mind when they created these shoes: power delivery and efficient transitions. Featuring an Ergo Bonded upper for a super light construction and the lightest Mavic outsole available, these shoes weigh in at just 240 grams while boasting an energy transfer index of 100. With the help of the large velcro Ergo Tri Strap securing the shoes during T1 is easy as you jump on the bike. While the lightweight mesh upper wicks wet sockless feet dry. Compatible with three-bolt road cleats.

  • Ergo Strap Carbon SL, lightweight carbon fiber advanced closure system.

Great Aero shoes

I got this pair for my first Ironman, and I was impressed with the quality of the shoe, overall i think it is one of the best deals out there especially at this price, here are some things i really like

-Light & very stiff ... first thing you will notice about this shoe is how light and incredibly yellow it is. This pair also has a minimalist design, simple but effective. For stiffness, the sole and back panel are full carbon, so you will feel the stiffness while riding, your feet basically becomes a part of the bike.

-Ventilation - The front mesh coupled with the bottom vents work pretty good to keep a good air flow and prevents moisture build up.

-Good Fit - the fit was true to size, i ordered this online from the first time and the size i ordered worked great. The strap was pretty long at first, but after cutting it to fit my size, it works great.

-Comfortable ... The shoe is pretty comfortable, i don't feel any toeankle discomfort until maybe after 3 hours of riding, and its never bad.

-Color - while yellow is pretty strong color, it serves pretty good on the road if you want to be more visible.

overall, this is a solid pair of shoes, strongly recommended.
