If you are chasing a personal best this season, chances are your shortlist comes down to two shoes: the Nike Alphafly 3 and the Nike Vaporfly 4. Both are built around a full-length carbon plate and Nike's ZoomX foam, both have carried runners to world records and podium finishes, and both are among the most requested racing shoes at Runningoat. But they are not the same shoe, and picking the right one can genuinely change how your race feels.
What they have in common
Both shoes belong to Nike's super shoe family. Each pairs a responsive ZoomX midsole with a stiff carbon Flyplate that acts like a lever, helping you roll forward with every stride. Both are legal for road racing, and both are designed first and foremost for race day and fast sessions rather than daily training.
Nike Alphafly 3: maximum cushion and propulsion for the marathon
The Alphafly 3 is the shoe Eliud Kipchoge made famous. Compared with the Vaporfly, it adds visible Air Zoom pods under the forefoot and a taller, wider stack of ZoomX foam. The result is a shoe that protects your legs deep into the final kilometers of a marathon and gives a pronounced snap at toe-off.
Choose the Alphafly 3 if:
- Your goal race is a half marathon or marathon
- You want maximum cushioning and bounce late in the race
- You are happy to trade a little weight for more protection

Nike Vaporfly 4: the lighter, snappier racer
The Vaporfly 4 is the latest evolution of the shoe that started the super shoe era. It is noticeably lighter than the Alphafly, sits a little lower to the ground, and feels more agile through corners and pace changes. Many runners find it the more natural-feeling of the two.
Choose the Vaporfly 4 if:
- You race everything from 5K to the marathon and want one racing shoe
- You prefer a lighter shoe with a more direct ground feel
- You also want a weapon for interval sessions and tempo runs

So, which one should you buy?
There is no wrong answer here, only the right tool for your race. As a simple rule: pick the Alphafly 3 for the full marathon, where its extra cushion pays off most, and pick the Vaporfly 4 if you want one versatile racer for everything from the 5K to race-week workouts. Whichever you choose, every pair at Runningoat is 100% authentic, ships free, and comes with 30-day returns.
