The Sidi T-4 Air shoes are suitable for Triathlons because of the simple retention system and large heelstraps, allowing for quick changes. The breathable and quick to dry-properties further enhance their use in triathlons. The Politex material is fully perforated which ensures water can easily be drained, as well as providing optimal ventilation and comfort. The shoes are fitted with a soft liner, allowing you to wear them without socks. The two wide high-security velcro straps are simple and quick to close, offer a perfect fit, and plenty of security.
Extensive explanation size in cm
The size denoted in cm tells you how long the shoe is. This size was taken on the inside of the shoe measuring from the heel to the toes. In order to determine what size you’ll need, you can measure your own foot. Do this by placing a piece of paper on the floor tucked against the wall. Stand on the paper with your heel against the wall. Draw a line at your big toe. Measure the distance between that and the wall, and add approximately 5 mm. The number of centimeters is the size in centimeters found on our website. Which specific EU/UK size you need can differ between brands. This is because each brand uses their own boot tree, causing the shoe to be bigger or smaller than the size would suggest. This is why we’ve added the size in centimeters for all of our shoes. We’ve also categorised our shoes in three different groups: narrow, medium, and wide. In order to determine the width of your foot, you can use this table.
