Power, precision, and comfort, together at last.

Humanity has a rich history of causing pain and suffering in complex ways, but triathlons have to be one of the more convoluted and exquisite methods we've devised, particularly for your feet. As it turns out, though, performance and pain don't have to go together, so Louis Garneau designed the Tri-400 Women's Cycling Shoes to offer a combination of comfort, power, and low weight that'll have you ripping across the line without sacrificing your feet.

Comfort and power start with the fit, which the Tri-400 dials in using a combination of a BOA IP1 closure and a reverse Power Flex hook-and-loop strap. BOA provides an infinitely adjustable and pressure-point-free fit, and the Power Flex passes from the outside of your foot to the inside, locking your foot in place and allowing easy adjustment while you're in the saddle. At the heel, Garneau's HRS-400 membrane features a thin, one-way neoprene membrane that lets your foot slip in but doesn't let it slide out, and the Ice Fill Ergo Air ventilated footbed works with the shoe's air channels and partial mesh upper to keep your feet cool and dry. Ice Fill is also antimicrobial, so your shoes won't take on unpleasant odors while you pile on the miles.

To be an effective race shoe, comfort has to go hand-in-hand with power and low weight. In the Tri-400, the Carbon Composite HM X-Lite outsole is rigid, thin (just 4.3mm), and ultra-light, giving you a pedaling platform that doesn't waste any of your energy output. The rigid microfiber upper helps eliminate flex and wasted energy, too, so you can conserve more energy for the run.


  • Familiarity: I returned this product before using it
  • Size Bought: 39

I wear size 8, sometimes a size 8.5 because my second toe is longer than my big toe. I ordered a 39: but the shoe felt too small. Toe was hitting the edge. Returned it & ordered size 40.
The look, feel and fit of the shoe is great. I love the boa closure. Ensures a really nice fit.
