Designed for the high-performance, high-mileage triathlete who wants the best, Sidi’s T2.6 shoe features the patented Full Carbon sole that strikes the perfect balance of power transfer and foot health. The triathlon-specific upper has a plush, brushed interior for sock-free comfort. The notched top strap opens away from the drive train and the large heel loop makes for fast transitions. A replaceable heel pad improves walkability. Fits all 3 bolt pattern cleats and Speedplay with adaptor .
They are designed for hours of comfortable riding with or without socks. You'll be surprised to see there is no 'tongue' with the Side T2 shoes so they feel very comfortable. They are lightweight but made with strong materials (Carbon fiber sole, fine leather). This type of shoe was created specially for riding, not for walking.
