A great Triathlon specific cycling shoe must be quick to get into and deliver comfort and outstanding pedaling efficiency for both short course events right through to Ironman biking distances. The T-5 Air Road Shoes ticks those boxes with ease. Immediate comfort comes by the way of the advanced and eco-friendly upper material - 'Politex'. This material gives you a supple and comfortable fit and, thanks to its unique construction, is highly resistant to ripping, abrasions, stretching and fading. It's the perfect choice to keep the shoes in perfect condition for all your training and triathlon racing needs. For lightning-quick transitions, the T-5s feature a wide foot opening that's quickly adjusted to your preference via the dual strap system. The heel loop makes it impressively easy to get your foot in place too, even on the go, letting you get a jump on your competitors. With the Sidi heel cup, you'll also enjoy a solid and stable pedaling platform with your foot held in just the right position even during longer events. 12 Carbon Composite Sole Once you're on the bike, the 12 Carbon Composite Sole provides instantaneous power transfer, getting you up to speed with optimal efficiency. The blend of nylon and carbon fiber gives a sole that is both rigid and lightweight letting you maintain your speed without power loss. The carbon fibers also ensure the stiffness rating won't degrade over time or be affected by heat or humidity. A performance sole unit engineered to last and last.

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

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.
Great fitting show but hard on your feet and even with great socks feet still feel cold … but a great show for the price
Just as described recommended
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.
