Technical information

Why use a triathlon-specific shoe for the cycling leg?

As you know, triathlons consist of 3 disciplines and 2 triathlons. Whatever your race objective, transitions are always stressful. That's why we are offering a triathlon-specific cycling shoe which is easy to pull on and off, while ensuring excellent barefoot comfort, sparing you the effort of putting wet socks on when you come out of the water.

How to choose the right size

Choosing a cycling shoe is similar to choosing a running shoe; we recommend selecting one size above your everyday footwear so that your foot is not compressed on use, particularly at the toes. Make sure they are not too big either so that your foot doesn't move around in the shoe. Check that your heel doesn't lift off the shoe once tightened to confirm your choice.

Triathlon cycling leg with or without socks?

That is the question! Putting socks on wet feet during the 1st transition can be difficult, scary as it may be, depending on the distance, to try the cycling leg without socks for fear of discomfort and overheating.
With the Triathlon Aptonia shoes, you can cycle without socks thanks to their seamless, extra soft inner layer. This enables a smoother first transition and comfortable cycling.

Are triathlon shoes as effective as road bike shoes?

These triathlon shoes will allow you to manage the 2 transitions effectively, and more importantly, help you to perform the cycling leg as well as possible.
In terms of shoe construction, we offer an adjustable instep support system with the ATOP buckle. The nylon sole offers an excellent compromise between comfort and rigidity, while the slipper, made entirely of mesh, is perfectly shaped to your foot and ensures great ventilation.
