Nike Alphafly 1 vs Alphafly 3 vs Vaporfly 2: Which Racing Shoe Still Makes Sense

We take the original Alphafly out for a hard speed session and compare it against the Alphafly 3 and Vaporfly 2 to see how the classic racing shoes stack up today.

Introduction

Few racing shoes carry the reputation of the original Nike Alphafly. It is the shoe that started an era: a full bed of ZoomX foam, a carbon fiber flyplate, and a pair of Zoom Air units under the forefoot. Recently, a brand-new pair went through a proper hard speed workout, including 6x1 km repeats and 4x400 m reps, and this is how it stacks up against the Alphafly 3 and the Vaporfly 2.

Design and Construction

The Alphafly 1’s midsole is the headline. You get the classic ZoomX foam with its crinkled texture across a full-length bed at the rear, which transitions into a split forefoot: a top layer of ZoomX sitting over an Air pod right under the ball of the foot, with the carbon fiber flyplate in between. In the Alphafly 3, that forefoot gap was closed up completely.

The upper is the Atomknit, and it looks like the stretchy, softer predecessor of the upper on the Alphafly 3. The original needed a bit of a fight to get on foot, while the Alphafly 3’s upper is more structured and easier to slip into. Both carry the signature racer tail at the heel, a pointed swoop that Nike used across this whole generation of shoes, including the Vaporfly 2 and the Tempo Next%.

Weights Compared

On the scale, the Alphafly 1 came in at 234 g, with a second pair matching at 233 g, which is a good sign of quality consistency. The Alphafly 3 weighed in at 223 g, only about 10 g lighter across the generations. The Vaporfly 2 was the lightest of the three at 214 g, roughly 20 g lighter than the Alphafly 1.

Given that this is Nike’s most expensive shoe, the consistency between two pairs of the Alphafly 1 is worth noting.

How It Felt on a Hard Speed Session

This was the fastest workout of the training block: six kilometer repeats and four 400 m repeats, with paces in the low five-minute-per-mile range. The Alphafly 1 felt aggressive and raw, encouraging a grip-and-rip style right at the front of the foot, with good bounce off the forefoot.

The famous midfoot arch is real. It pokes up into the middle of the foot right away, and it was noticeably uncomfortable, especially while walking before the reps. The Alphafly 3 has more cushion under the midfoot and does not have this issue.

Alphafly 1 vs Alphafly 3: What Changed

Side by side, the two shoes share the same spirit and construction, but Nike made a few clear moves with the third version. The base was widened for more stability, the forefoot gap was closed, some foam was removed from the core to save weight, and the upper became a touch more structured. The Air units under the forefoot remain in both.

The verdict after the workout: the Alphafly 3 feels more comfortable, smoother, possibly a little faster and bouncier, and overall a more cohesive package. But the difference is small, maybe five percent. If you love the aggressive, raw ride of the original, the Alphafly 3 keeps that character while ironing out the rough edges.

Vaporfly 2: The Lighter Alternative

The Vaporfly 2 remains a favorite as a half marathon shoe. Its setup at the heel is very similar to the Alphafly 1, including the racer tail, but the front end is simpler: just ZoomX foam and the plate, with no Air pod. At 214 g it is the lightest of the three, and it still stands as one of the all-time great racing shoes even though a later version did not quite match it for the same runner.

Do You Still Need the Original?

A fair disclaimer: you do not need a specialized carbon-plated shoe to do a speed workout, and you certainly do not need a hard-to-find retro pair at a premium. But for runners getting down into the low sixes and fives per mile in workouts, carbon-plated racing shoes genuinely help. They add confidence, speed assistance, and that rewarding pop when you are grinding at the edge of your ability.

The Alphafly 1 has aged remarkably well. Its silhouette would not look out of place as a current release, and the ride is still very much a modern super shoe. Compared against anything else on the market, it is easy to see why fans of this shoe are reluctant to try the alternatives: it feels unique. That said, the Alphafly 3 is the more refined, more comfortable version of the same idea, and it is the better pick for most runners today.

Conclusion

The original Alphafly still lives up to its legend: aggressive, fast, and bouncy off the forefoot, with a raw character that some runners still prefer over anything newer. The Alphafly 3 is lighter, wider, smoother, and more comfortable, making it the smarter everyday racing choice. The Vaporfly 2 remains the lightweight favorite for shorter races. If you chase nostalgia and the OG feel, the Alphafly 1 delivers; if you chase the best overall package, the Alphafly 3 wins.
