Specs at a glance
Reviewers who wore both
Direct paired observations — reviewers who actually ran in both of these and wrote the contrast. This is the strongest comparative signal on the page.
Alphafly is the better pick for half marathon and marathon distances thanks to more cushioning; V4 is now polarized as the 5K/10K option
Alphafly 3 can do everything from short to long distances; reviewer wants more bounce and would have been fine using Alphafly 3 instead
Vaporfly 4 is lighter and leaner but less propulsive with less cushion, now better suited to shorter distances
Megan still picks the Alphafly for the full marathon and the Vaporfly 4 for the half; Thomas might pick V4 over Alphafly even for the marathon because it's two ounces lighter
Clearer distinction now — Alphafly is the longer-distance bouncy option while Vaporfly 4 is for shorter races
Alphafly 3 is the marathon/long-distance race shoe in the lineup; Vaporfly 4 sits below it as the shorter-distance speed option
Vaporfly 4 midsole appears to mix elements of the Alphafly 3 and Zoom Fly 6
Alphafly is significantly more expensive and heavier (269g) but a happier marathon cruiser with more foam and Air Pods; Vaporfly 4 is lighter, more nimble and faster over shorter distances
Vaporfly 4 is lighter and nimbler but Alphafly 3 better for the marathon, especially for heavier runners
Alphafly is the marathon shoe and a cruising machine; Vaporfly 4 is now clearly separated and aimed at half marathon and below
Alphafly has extra heel width, making it the more stable option Nike positions for the marathon masses versus the narrower Vaporfly 4
Less cushioned, smaller base, less bouncy; reviewer prefers the Alphafly's bigger bouncy feel for marathons
Better all-round race shoe and far better choice for heavier runners and the marathon; superior traction
Reviewer notes Nike elites are increasingly racing in the Alphafly; the Vaporfly 4 carves out a leaner, shorter-distance niche
Vaporfly 4 is starkly different — much less shoe underfoot; reviewer prefers the Vaporfly because the Alphafly is 'a lot of shoe' and feels like the shoe is in charge of the runner
Vaporfly has thinner spoon-shaped plate closer to the ground, better for forefoot strikers at 5K/10K; Alphafly 3 plate is higher up thanks to AirPods, better for stride runners
Vaporfly still feels more direct and is preferred for 5K and 10K; Alphafly 3 is more cushioned and protective for longer distances.
About 1oz heavier (270g vs 235g in UK 11); wider everywhere, more cushioned, better lockdown with simpler lacing, and more durable outsole — preferred for upper, midsole and outsole.
Alphafly 3 is heavier but more cushioned, more propulsive, more bouncy, and more versatile across distances
Nike Vaporfly 4 — what reviewers say
Ride profile: high cushion , neutral stability .

EDDBUD says the Vaporfly 4 became one of his favorites after initially disliking it — great lockdown since the offset lacing was dropped, very light, and durable outside of sharp debris.
Fit:Sizing is a bit sporadic across colorways currently on sale.
In their words: "kind of become one of my favorites" · "great lockdown" · "very light shoe"
-
#4 carbon racer. Brings Vaporfly closer to Alphafly aesthetic — execution issues but still fun at fast paces. Extremely lightweight.
In their words: "still very fun for running very fast" · "extremely lightweight shoe" · "execution issues going on with this shoe"
-
A solid but limited race shoe that feels light and quick at shorter distances but lacks the midsole and bounce for longer races, especially the marathon.
Ride:Lighter and closer to the ground than Vaporfly 3 with snappy, responsive ride and reliable landings; lacks midsole bounce and feels limited at longer distances; works well for shorter, faster efforts.
Fit:Roomier than expected for such a lean, small-looking shoe with plenty of space for the big toe; race-hugging without feeling cramped, with some heel slipping fixable with attentive lacing; stay true to size.
In their words: "designed for shorter distances" · "doesn't have enough midsole for me" · "a half marathon sweet spot"
-
Not a flop — still a top-tier super shoe, but Nike has narrowed its purpose to 5K and 10K racing, making it less versatile than prior Vaporflies and a poor pick for half marathon or marathon distances.
Ride:Lightest Vaporfly yet, makes 5K pace feel smooth and efficient; ZoomX shows quick compression where the foot lands
Fit:Best-fitting Vaporfly to date with a slightly more narrow forefoot, traditional tongue and a secure spike-like lockdown; no heel slipping for Ben
Nike Alphafly 3 — what reviewers say
Ride profile: high cushion , balanced feel , high energy return , neutral stability , moderate rocker.
-
EDDBUD highlights the Alphafly 3 as an ideal marathon option — plenty of cushion and a wide base keep it stable despite the very soft heel.
In their words: "a very wide base as well" · "not really unstable at all" · "ideal marathon option"
-
Ben's marathon PB shoe — a top super-shoe pick with PEBA foam and carbon plate, offering exceptional protective cushioning for long race distances.
In their words: "ran my personal best in the marathon"
-
The Alphafly 3 is eliminated in the group stage, described as a former great that is aging gracefully but no longer at the top.
In their words: "a former great, aging gracefully, but still not quite getting through"
-
WINNER of Megan's knockout race-day bracket — her ultimate race-day shoe.
Ride:Forefoot Air Zoom pods give it the edge over the Vaporfly 4. Megan's race-day pick regardless of distance (except Vaporfly 2 which she disliked). Comfortable upper. Heavier than the Metaspeed Ray but worth it. Feels great in the late miles of a marathon.
Who should buy which
