Buy yourself a minute or two.

If you’ve ever raced a triathlon wearing traditional cycling shoes, you know that trying to adjust multiple straps while balancing on your bike isn’t always easy. Sidi’s T3.6 Shoes make your transitions faster, while also giving you the on-the-bike power transfer you crave.

Rather than using its ratcheting Ergo buckle system, Sidi opted for a simple two-strap, hook-and-loop system to secure the Lucido synthetic leather uppers. The system is a "burrito-wrap," meaning that one layer wraps into the other, creating a near seamless inside. This style, combined with the wide straps, hugs your feet to give you that second skin feel, which is optimal for triathletes who prefer going sockless on the bike.

A rear heel pull tab helps to pull your shoes on fast so you don’t lose valuable seconds in transition. The uppers are placed on Sidi’s Eleven Carbon Composite Sole, which is a stiff and light 3K carbon fiber weave that is inset into a carbon nylon matrix.

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: 46.5

I ordered this shoe a week before an Ironman. Rule #1 - never try anything new for a race, which I can say now is wrong. I took the shoe for a 20k ride 3 days prior to the race and it just feels like all Carbon Sidi's, so I decided to start with it.
I'm using the Sidi Wire Air Carbon Shoe for my road bike and training.
For the price I paid and the quality and comfort you get with this shoe, I have to give it a 5 star.
All Sidis run really small, so you have to know your size. I'm a EUR 44, but I need the Sidis ina 46.5.
