Inspiration Drawn From the VaporflyIt's no secret that the Vaporfly is one of Nike's strongest performance shoes, so the Nike Men's Zoom Fly 3 was crafted to follow in their image. If you're a distance runner who pounds away on your feet, these can help take some of the load off with a full-length Nike React midsole. This midsole provides extreme cushioning without adding a ton of weight, helping you maintain your smooth ride without having to huddle off on the sidelines.Run Harder, Faster, StrongerRunners always want to improve their times, and with the Nike Men's Zoom Fly 3, that might finally be possible. They include a carbon fiber plate that gives you supreme energy return by shrinking or expanding to fit your stride. Paired with a lightweight upper that won't drag you down, the result lets you maximize each step. Nike Men's Zoom Fly 3 features: Lightweight upper reduces the weight of the shoe so you aren't dragged down. Arch band across the laces reduces pressure on your instep. Low collar conforms to your foot to eliminate unnecessary fabric. Carbon fiber plate shrinks or expands to offer flexibility in your stride. Rubber outsole on the heel and forefoot keeps you from slipping.
