Heartbreak Hill Running Company

Neutral | High Cushion | 8mm Heel Drop

The R.A.D® UFO is a road-running Super Trainer - designed to build speed across distance.

At the UFO’s core is SUPEFOAM™ - a dual-layer PEBA blend. The soft layer improves running economy and reduces fatigue by cushioning each step, while the firm layer delivers powerful energy return with every stride - a catch-and-release system.

The flowing rocker and sculpted heel bevel have been designed for smooth transitions and dynamic toe-offs, keeping the runner in perpetual motion - on loop.

Engineered for comfort and speed across distance, the UFO is a precision instrument for every phase of a runner’s training, ideal for long runs, progression sessions, and threshold work.

Designed for road-running, not the trail.

CR designed this as an evolution of the everyday run tee — built for airflow and shaped for versatility.

The new adjustable cinch system lets you decide the silhouette. Wear it relaxed and open for an easy, casual drape. Cinch it down when the effort stretches out, eliminating excess movement at the waist and creating a more secure, dialed-in feel. It’s subtle, but functional — giving you airflow and freedom of expression.

The fit stays intentionally boxy, easy through the shoulders and chest, so it layers cleanly over a singlet or under a shell without fighting the rest of your kit.

The Cutdown Tank is a natural progression and layering piece for CR women’s collection. Inspired by training sessions built around progression— where the reps get shorter as the pace is pushed — the silhouette follows the same idea. Cut from CR's favorite 110gsm Italian jersey fabric, it has a flattering, cropped silhouette designed specifically to layer over CR's ever-expanding women’s performance pieces. Lightweight and made to move, it’s a training layer built for putting in work.

The Vaporfly 4 is a lean, mean, mile-eating machine. We trimmed weight in the midsole, outsole and upper from the Vaporfly 3 without sacrificing performance. The result is a lighter, more propulsive all-around racing shoe that’s trusted from the mile to the marathon.

Performance Approved
The handwritten number on the midsole salutes the wear-testers who put these shoes through our rigorous test process to give you the best performance possible.
Full Speed
A full-length carbon fiber Flyplate provides a propulsive, racing feel. A higher angle of the plate and lower heel-to-toe drop compared to the Vaporfly 3 give you an improved propulsive feel.
More Energy Return
Nike ZoomX, our most responsive foam, just got faster. Running from heel to toe, it unlocks even more energy return than before thanks to a slight midsole reduction, giving you a bouncy, feathery feel.
Less Weight
Engineered mesh offers improved comfort and a disappearing feel on your foot. It helps reduce the weight of the shoe while supplying a more consistent fit. And we reduced the size of the heel and tongue, saving even more weight.
Light Feel
See how the midsole bulges out by the heel? We designed it that way to help reduce weight on the inside of the foot to give you a more stable ride. We reduced the weight of the outsole by using a thinner rubber compared to the Vaporfly 3. You still get the same reliability, just without any unnecessary thickness.
What's New About the Vaporfly 4?
We took a race-car approach when updating the Vaporfly 4, making many minor tweaks so you can pursue major gains. We trimmed weight in the midsole, outsole and upper without sacrificing performance.

Behind the Design
Jakob's favorite colors and repeating lines nod to his mental approach. His tattoos and gold rings inspired details that’ll shine when he kicks it into high gear. Nordic stars on insoles nod to his family.
Engineered Upper
New yarns and engineered upper enhance breathability and comfort. The upper's conforming fit gives a disappearing sensation that is built to go the distance. Heel is reinforced to help improve stability.
ZoomX Foam
Full-length ZoomX foam, Nike’s lightest and most resilient foam, delivering a high level of energy return with every stride you take.
Stable Connection
Four permanent spikes help reduce the weight of the plate and create a wide, flat platform for a stable connection to the track.
Carbon Plate
Carbon unlocks plate response and helps reduce weight. The curved design gives you a propulsive feel.
What's New?
A slightly wider midfoot and forefoot compared to the previous iteration improve the feeling of stability on straightaways and especially around the turns.
