Nike Vaporfly 4 Reviews

They set a 17:32 5k PB in the Vaporfly 4 after a 50 km break-in and say it also works very well for marathon training long runs, better than the Zoom Fly 6.

Ran their first marathon of the year in these and says they felt great the whole distance.

Shockingly light (153 g at 25.5 cm) with a better fit and smooth leg turnover: a real weapon for the back half of a marathon. If you want the VF3's explosive pop, you may find it slightly lacking.

A sub-3.5 runner who ignored the 'half only' warnings: at 30 km he felt surprisingly fresh. He faded only on small climbs after 35 km, it was his easiest marathon finish yet, and his hip held up. 3:12 on a course that doesn't suit him.

A race-and-shoe story: landing on the balls of his feet, he felt the propulsion 'like pulling a Ferrari onto the Autobahn'. He finally found a runner's high at the Ottawa Marathon, and runners at the finish asked about his shoes.

A snappy, versatile road racer: exceptionally fast for intervals and marathon-pace runs. The extra arch room helps high arches. On 15–16-mile workouts it firmed up and one tester wished for the Alphafly. Heel slip is listed as a con.

After PB-ing from 5K to half in it, he raced Seville in it: five reasons to consider it for a marathon despite the usual caution. It works best for engaged forefoot or light midfoot strikers. Grip isn't as confidence-inspiring as the VF3, so a wet race would give him pause.
