Shoe Entry/Exit
The biggest difference between cycling shoes and triathlon shoes is in how they are put on and removed. In a cycling race, riders have their shoes on and ready before they get on their bikes, while triathletes often start riding their bikes and put their shoes on while they ride. To speed up the transition, most triathlon shoes have larger openings to allow for a slip-on type of entry that is secured by a simple fastener, often Velcro.
Fasteners
Cycling shoes may use laces, zippers or a ratchet-based fastening system, but in the interest of a quick swim-to-bike transition, triathlon shoes are designed to have the simplest fastening method possible. Most triathlon shoes are fastened by a single Velcro strap across the top of the shoe, and many also feature a heel loop as well. To further speed up the process, most Velcro straps on triathlon shoes are reversed, with the open end facing the arch of the shoe, to allow wearers to quickly "slap" their shoes on.
Breathability
Since triathletes are going from the swim right to cycling, triathlon shoes are quick to dry. Most triathletes put their shoes on with wet feet, so shoe designers have made a concerted effort to make shoes dry quickly, as excessive moisture in shoes often leads to blisters. Most triathlon shoes are made with synthetic materials that don't retain moisture and copious amounts of mesh to allow air to pass through the shoe, drying the riders' feet quickly as they race.
Seamless Interiors
In contrast to cycling shoes, triathlon shoes are meant to be worn without socks. Putting on socks as well as shoes during the swim-to-bike transition would sacrifice precious seconds to a racer's time, so triathlon shoes are made for comfort sans socks. Seamless interiors and breathable materials ensure a comfortable ride for triathletes. Many triathlon shoes have interiors lined with nylon mesh and microfiber, synthetic materials that feel soft against skin while keeping it dry.
