Overview
Nike's two carbon-plated super shoes have dominated elite racing for years. The Vaporfly 4 is the lighter, more versatile racer. The Alphafly 3 is the maximum-stack marathon specialist with Air Zoom pods under the forefoot. Both use ZoomX foam and a full-length carbon fiber plate.
Weight
The Vaporfly 4 comes in at 5.9 oz in a men's 9 — about an ounce lighter than the Alphafly 3 at 7.0 oz. The Vaporfly 4 actually got lighter than the version before it, and you feel that immediately in the first mile of a 5K or 10K.
Carbon plate and propulsion
Both have full-length carbon plates. The Alphafly 3 adds two Air Zoom pods in the forefoot for extra bounce, which makes it feel springier but less settled underfoot. It takes practice to run in efficiently, and it rewards runners who land forefoot-first.
Stack height and stability
The Alphafly 3 stacks 39.5mm in the heel and 31.5mm in the forefoot. The Vaporfly 4 is noticeably lower at 35mm and 29mm, which makes it the steadier of the two — particularly in the last few miles of a marathon when your form starts to go.
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 specifically for the marathon, where its extra cushion and bounce earn their keep over 20-plus miles.
Price and availability
The Alphafly 3 lists at $285 and the Vaporfly 4 at $240. Both sell out fast in popular sizes, and neither is reliably stocked through Amazon — you will usually have better luck buying direct from Nike or from a Florida specialty running store that carries race-day shoes.
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.
