Nike Alphafly vs Vaporfly: which is better?
The Vaporfly 4 is the better pick for most runners. It is about an ounce lighter (6.7 oz vs 7.7 oz in a men's 10), $25 cheaper at list, and works from the 5K to the marathon. The Alphafly 3 is better only for the marathon, where its taller stack and forefoot Air Zoom pods help in the last 10K.
Overview
Nike's two carbon-plated super shoes have dominated road racing for years. The Vaporfly 4 is the lighter, lower, more versatile racer, and Nike calls it the lightest Vaporfly yet, roughly 10% lighter than the Vaporfly 3. The Alphafly 3 is the tall marathon specialist, with two Air Zoom units under the forefoot. Both use ZoomX foam and a full-length carbon fiber plate.
Weight
Nike lists the Vaporfly 4 at about 6.7 oz (190 g) in a men's 10 and 5.4 oz (152 g) in a women's 8. The Alphafly 3 comes in at about 7.7 oz (218 g) in a men's 10 and 6.1 oz (174 g) in a women's 8. That one-ounce gap is the first thing you notice in the opening mile of a 5K or 10K.
Heel-to-toe drop
The Vaporfly 4 has a 6mm drop, down from the 8mm of earlier Vaporflys. The Alphafly 3 keeps an 8mm drop. If you land on your midfoot or forefoot, the lower Vaporfly feels more natural. Heel strikers often settle into the Alphafly more easily.
Stack height and stability
Nike does not publish stack heights for either shoe. Running retailers list the Alphafly 3 at 40mm in the heel and 32mm in the forefoot, right at the World Athletics road limit, and the Vaporfly 4 at 36mm and 30mm. The lower Vaporfly is the steadier of the two, which matters in the last few miles of a marathon when your form starts to go.
Carbon plate and propulsion
Both have full-length carbon plates. The Alphafly 3 adds the forefoot Air Zoom pods for extra bounce, which makes it feel springier but less settled underfoot. It takes practice to run in efficiently, and it rewards runners who stay up on their toes late in a race.
Best distance
The Vaporfly 4 works from 5K to the marathon and is the easier shoe to justify if you only buy one. The Alphafly 3 is built for the marathon, where its extra cushion and bounce earn their keep over 20-plus miles.
Price and availability
On Nike.com the Alphafly 3 lists at $295 and the Vaporfly 4 at $270, with some Vaporfly 4 colorways at $280. Both are often marked down by colorway, so check before you pay full price. Amazon stock comes and goes by size, and you will often have better luck buying direct from Nike or from a Florida specialty running store that carries race-day shoes. Nike's site also lists an Alphafly 4 as coming soon at $280. We will update this comparison when it ships.
Who should buy each
Choose the Nike Alphafly 3 if: you are racing marathons and want maximum cushion and propulsion, you are comfortable in a tall, bouncy shoe, and budget is not the deciding factor.
Choose the Nike Vaporfly 4 if: you race multiple distances from 5K to marathon and want the lighter, steadier, more versatile super shoe for less money.

wb_sunny Why This Matters for Florida Runners
For Florida's flat marathon courses — Miami, Space Coast, Tampa Bay — the Vaporfly 4 is the natural pick. Flat terrain does not demand the Alphafly's extra cushion the way a rolling course does, and the Vaporfly's lighter weight helps in Florida race-day heat and humidity. Florida's fast, flat courses are exactly where carbon-plated shoes produce their best times, which is part of why so many runners chase PRs and Boston qualifiers here in the winter racing season.
