The Sidi T-4 Air Cycling Shoes are built with a host of features designed to help triathletes shave valuable seconds off their time. Features a tri-specific enclosure design focused on mindless entry and exits when switching from one phase to another. Sidi knows triathletes have different cycling-shoe requirements. So, they incorporated a two-strap closure system mated with a 'burrito-wrap' upper, with one layer of the upper wrapping over the other. This allows you to quickly dial in the volume of the shoe while rolling out of T1. For extra time savings, theres a durable pull-tab at the heel. Sidis unique balance of tradition and innovation, style and comfort, make SIDI sporting footwear exceptional in the industry.
