The Diadora Tornado Road Shoe is designed with all the bells and whistles of the Proracer 3, but is constructed with materials that won't set your wallet ablaze.
One of the differences you'll see between the Proracer and the Tornado is the construction of the sole. While the Proracer is carbon fiber, the sole of the Tornado is Diadora's Performance Road CR. This is a composite reinforced sole rather than full carbon. It is stiff for optimal power transfer, but it does add a few grams of weight to the shoe. Like the Proracer 3, the Tornado shoes include a removable heel pad. This pad is made of Duratech rubber for grip as well as abrasion resistance. This heel pad helps to lock your heel in place to avoid slipping, which reduces friction to your achilles tendon. It is attached with one screw and is removed simply by lifting the insole of the shoe. A heel cup cradles the foot to provide added support and comfort. The insole is constructed from Hi-Vent, a perforated EVA foam. The perforations in the insole allow moisture to wick away from your feet — this keeps you dry and comfortable.
The uppers of the Tornado are synthetic leather and feature Diadora's Suprell Tech - Morpho AM Cage technology. This cage, constructed of TPU, keeps the shoe molded to your foot. The fit of the Tornado is a Race fit. This fit utilizes the features that Diadora's professional riders use — a fitted forefoot, comfort and support in the middle section of the foot, and secure heel retention. This combination supports an ergonomic fit as well as optimal power transfer. The shoes are secured closed using an adjustable buckle with four points of adjustment to fit a variety of feet. Two hook and loop straps also tighten the shoe.
The Diadora Tornado Road Shoes are compatible with 3-hole road cleats and weigh 279 grams. They are available in sizes 37.0, whole and half sizes 38.0 to 46.0, and size 47 and in the colors: White/black/red and Silver/black/red.
