At first glance, triathlon shoes may not seem much different than standard cycling shoes, but when you've spent your fair share of time struggling through transitions and stuffing bike-blistered feet into running shoes, you know how important a tri-specific cycling shoe is. Sidi's T5 Air shoes are among the best of the bunch, with a fit that's tailored for female triathletes, a construction intended to mix the best of power and comfort, and features that are made to make transitions and on-the-go adjustments as quick and easy as possible.
