Triathlons can be won and lost in the transition zones, so it's important to have your switchovers dialed. Slipping wet feet into snug shoes can cost you valuable time, so Diadora made sure the Phantom Men's Shoes are easy to get on and off, without sacrificing the fit you need to make time on the ride. They're designed with Diadora's Race Plus TPU upper, which fits as snugly as the name suggests, but has extra room in the toebox for easy ons and comfortable sockless riding. Even if your foot is wet, the Morpho AM cage will lock your heel in place and prevent side to side slippage, so you don't develop blisters or lose power to a loose fit.To further improve the fit, Diadora built the Phantom with dual ring adjustments for the hook and loop straps. You can choose which ring you thread the strap through, to increase or reduce volume depending on the width of your feet. Underneath, a carbon and fiberglass reinforced Sport Road sole serves up a killer blend of stiffness and comfort, so you can put power to the pedals without killing your feet.
