Sidi II Triathlon, £149.99
Sidi's specialist tri shoe is more than just easy on the eye. The highly perforated synthetic leather upper, which is open down the centre, cools and dries your feet and drains water efficiently. Its double Velcro straps are more of a hassle than a big single strap but they do secure the shoe around your foot. What you're really paying the extra money for is the carbon composite outsole that is by far the stiffest of the three on test, particularly through the middle of the outsole.
