Sidi T3 Carbon Air Triathlon Shoes

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 upper is constructed of Sidi's proprietary Tecnomicro fabric that has been specially perforated for additional ventilation and air flow. Technomicro provide excellent support but remains thin, breathable and extremely stretch resistant. The Vernice finish adds durability and and makes the shoe easy to clean and care for, both of which help extend longevity. The interior of the upper features a soft, brushed plush material which is ideal for wearing the T3 sock-less. This Sidi specific material wicks and dries rapidly.

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.

Excellent construction, comfortable, and relatively easy to get in. Can be a little harder to get out while riding. The two straps hold the foot well. The only little complaint that I have is that the top strap folds toward the inside and its end, although covered with Velcro, curves up a bit with time and start rubbing on the crank. This might not be a problem with big feet, but mines are moderately long (US 10, EU 44) but slim. Hence the top strap is almost too long. The leather is of very good quality and the shoes drain well. Very comfortable riding even without socks; I never had a blister even after century rides in hot weather. I have been training and competing in triathlon with these shoes for approimately 6 months now and I am quite satisfied.

Pros Excellent construction, comfortable, good support

Cons Top strap can rub on crank
