    The T4 Air Carbon is a great shoe.  Comfortable with or without socks.  Be careful to get the right size as the toe is narrower than other brands I've used--I took one size larger. Also, customer service is outstanding--couldn't be better.

  • 11/6/2018 !!Transition friendly Tri shoe!!

    5 Review Stars By Swimbikerun

    Going from a regular cycling shoe doing triathlons, to a tri shoe specific in the Sidi's is complete satisfaction. The new shoes took time off my transitions in both triathlon's I competed this year and the air flow across the shoe is complete in every way. The look is amazing as well would definitely recommend this shoe to anyone wanting quality Italian craftsmanship.

    The Good nice carbon sole, ventilation, arrived quickly.  

    Not sure of the size, ordered a 43.5, the sole of the shoe have a printed "43" on them and then a sticker "1/2" was added to the sole.  The shoes feel snug.  Previously I wore shimano's carbon tri shoes and they said "43 1/2" and felt roomier than these shoes.  

    It may take some getting used but these shoes rub / press on the top of my foot much more than previous shimano shoes even with socks on after 150 miles they still seem uncomfortable.

  • 7/3/2018 Great triathlon shoe

    5 Review Stars By Dan Gabbert

    I'm a 10.5 and I ordered several different pair of triathlon bike shoes over the internet. In the SIDI the 45.5 is too big. In other shoes the 45 was too small. I'm trying the 45 to see if it fits.
    The shoes are really comfortable, easy on and easy off. I used them in one race and they were great, albeit a bit too big and I had too much sliding around even with socks on.

    Sized these off of my cycling shoes and they fit just the same. Needed Tri shoes for quicker transitions and these work well for that.

About This Brand


SIDI® was founded in 1960 by Dino Signori whose love for cycling steered the company away from mountaineering footwear to bike shoes. In Maser, Italy, SIDI was a pioneer, creating many features that either improved on the first bike shoe models or were the first.

The very first SIDI bike shoe was made with adjustable screws. Because of this, cyclists stopped nailing cleats into the bottoms of their bike shoes. Another innovation that SIDI started was creating a SIDI bike shoe that had a Nylon sole for durable stiffness. SIDI also created the first modern bike shoe that used Velcro® in place of laces. They were even the first to make mountain bike shoes with lugged rubber soles for improved stability and durability. They also innovated style when they were the first to have multicolored bike shoes on the outside and the inside with a 2-colored sole.

They are still improving on their SIDI bike shoes by continuously testing and studying research. This led to the birth of SIDI Aeronet Light, an aerospace material that allows some of the SIDI bike shoes to be 60 grams lighter without losing their shape or toughness. When you are cycling to get to the Kona Ironman® you know how every grams counts. Also, their SIDI High Security Velcro® piece was the first no-slip bike shoe strap ever made. SIDI has respect for the past, they are the last company that designs and makes their bike shoes in Europe, with their sights set on the future.
