The Sidi T-5 AIR has many features that make this a great cycling shoe for a triathlete, yet it also has the race required stiffness and comfort for a bike racer. You will feel comfortable whether you are accelerating in a field sprint, putting in a time trial effort or churning the pedals as you ride in your T-5 Air up a mountain road. The T-5 is also very durable so it will last for many race seasons. The Twelve Carbon Composite Sole is made of nylon injected with carbon fiber. This combination results in a stiffer sole that lasts a long time so you can have shoes that efficiently transfer your leg power into the pedal for multiple seasons. As you pedal and accelerate, the reinforced heel cup keeps your foot in place while withstanding pressure, another feature that ensures the shoe maintains its high-quality race features and doesn’t degrade. To close the shoe, SIDI incorporated two straps with a grippy finish making them secure and easy to adjust on the bike or as you are making the transition from swim to bike. The oversized heel pull-tab makes it easy to pull on the shoe with no hesitation as you are speeding through the transition between two legs of a triathlon. The shoe is made with Politex material that has overlapping layers that complement themselves to provide a secure comfortable fit in a cycling shoe that resists tears, stretching and fading.

I used to wear 43.5 road shoes with a foot length of 27.2. Although I bought a size 44 this time, it was a little bigger, just a bit, I think it ’s very suitable without impact
Very nice tri shoes, light weight and very confortable, so far I'm very happy
Construction is suspect for a $250 plus carbon shoe, the buckle pulled out after just a couple races and the warranty department at Sidi wants nothing to do with you.
Very comfy shoe, easy to slide on and off with a lot of ventilation so your feet don’t get too hot.
Love the shoes. Very comfortable, in fact, the most comfortable I’ve ever owned.
This is a perfect shoes for me for my cycling activities. The sizing is perfect to size guide and hopefully can last longer to keep me on the road.
SIZE SELECTION - EURO 43. Typically I am a 43 and these fit perfect. I do have fairly widish feet but the fore foot area has plenty of room. ***My road shoes are SIDI Wire 2 Carbon Air which were ordered a 1/2 size up (43.5) as recommended by SIDI, these also are a very good fit. Then there was much debate what size to order the T5 Air however I settled on 43 thinking that the style of the upper shoe which is quite open and adjustable by the velcro straps plus I will not be wearing socks. The size choice was correctQUALITY - Solid shoes that will last a long timeCOMFORT - The inside lining delivers comfort with bare feet. Nothing irritating using these over a 90K TTPERFORMANCE - Nice and light shoe with good power delivery. Easy to get your feet in and out ... MoreSIZE SELECTION - EURO 43.
