Mavic’s new Cosmic Boas are a neat looking pair of performance road shoes, with super-clean lines. As well as the black pair pictured here, the white versions look a million dollars. Red/orange and a dark blue ‘total eclipse’ are also available.


Their elegant looks are partly down to their single Boa design with no secondary dial, strap or buckle – despite this I had no trouble achieving a snug and secure fit. Mavic also offers a less expensive Velcro-only Cosmic and pricier pro-level Cosmic Ultimate SL.

The nylon and fibreglass Energy Comp sole measures 50 on Mavic’s ‘index of energy transfer’ that maxes out at 100. In practice, it felt as stiff as most of us need unless we’re putting out Mark Cavendish-like amounts of wattage; I wasn’t. There’s sufficient stiffness that you certainly don’t feel like your watts are being wasted.

The single-piece breathable upper is very comfortable, with sufficient padding in all the right places. There are two sole vents and over 100 neat laser-cut perforations in the uppers.


In my experience, Mavic shoes come up a fraction smaller than most so I upped a size from my usual 42 to 42⅔, which proved to be a perfect fit, and the wide-ish toebox meant there were no cramped tootsies. In fact, Mavic offers an impressive 20 sizes from 36 to 48⅔, going up in ⅓ and ⅔ increments – or in UK measurements whole and half sizes from 3.5 to 13.
