SIDI's flagship bike shoe for triathletes, the Men's T-5 Air Triathlon Shoe, arrives with a series of must-have features and expert craftsmanship that make it race-ready out of the box.

Start with the vented Politex upper, which is constructed of several overlapping layers with different physical and mechanical properties. This compacted PVC material is then coupled to two fabrics (knitted fabric and felt) that is film dyed for durable, long-lasting color retention.

Made in strict compliance with environmental regulations that have earned it a "green product" designation, Politex offers strong resistance to rips, lacerations, stretching and fading.

On the back, a reinforced heel keeps the foot in an optimal position and avoids the shoe being deformed by extreme performance or prolonged pressure, while a replaceable polyurethane heel pad adds walkability.

Down below, a composite sole injected with molded carbon fiber in a matrix of nylon creates a lighter and stiffer sole that is less susceptible to changes because of aging or extended usage.

Rounding out the design of the T-5 Air Triathlon Shoe are smart details like two wide Velcro closure straps, heel hooks for easy-on, easy-off transitions, and bold black, yellow, and gray triangles tiled around the sides and on the top.
