"Men's Topo Athletic® Cyclone 3: The Cyclone 3 is a lightweight speed trainer built for runners who want a fast, energetic ride on up-tempo runs and races up to the half marathon distance. Topo Athletic designed this neutral running shoe around a 28 x 23 mm platform with a full Pebax Powered® midsole that keeps the ride lively and light without sacrificing responsiveness. If you're looking for a shoe that moves with you when the pace picks up, this is worth a close look.The mesh upper has been updated for improved durability while still offering excellent breathability - and the fit wraps the foot so naturally it almost disappears once you're moving. A 5 mm drop keeps the geometry low and connected, which suits runners who prefer a more natural feel underfoot. On the outsole, strategically placed rubber adds durability exactly where the shoe needs it most, trimming weight everywhere it doesn't. The result is a shoe that feels quick off the ground and stays comfortable through the miles that matter most.Why Our Fit Experts Love This Shoe""I put these on for a tempo run and immediately noticed how light they feel - like there's barely anything on your foot. The Pebax midsole has a real snap to it, and the 5 mm drop felt natural from the first stride. These are a great call if you're training for a half and want something that can handle both your hard days and race morning."" - Dave, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForIf you're a neutral runner who trains for half marathons or shorter races and wants a lightweight shoe that can handle tempo workouts and race day alike, the Cyclone 3 is a strong fit.
