With the T3 Carbon Air Triathlon shoe, Sidi was able to combine solid performance with the convenience of ease of entry and exit for fast transitions. Gone is the mono strap design for a more performance orientated and sensible dual strap closure system. The lower strap is located slightly farther down the shoe so you can get in and out by opening or closing the top strap. Once you're on the bike, you can then adjust the bottom strap to your liking.
The interior of the shoe features a soft, brushed plush material which is ideal for wearing the T3 sockless. This Sidi specific material wicks and dries rapidly. The upper is super-perforated for extreme ventilation.
Sidi's Eleven Carbon/Composite Sole is designed for maximum stiffness and power transfer, but it's also engineered with a small degree of controlled flex in the toe area, which relieves plantar tendon strain during the pedal stroke. This is a nice balance between a stiff performance orientated sole with long range comfort in mind. It was clear to us from the outset that this is one of the top Tri shoes we have ever laid our eyes on. If you're in the market, these are worth consideration.
