Nike ZoomX Vaporfly NEXT% 2: review and features

The Nike ZoomX Vaporfly NEXT% 2 is a road racing shoe that combines ZoomX foam, a carbon plate and low weight. It is most naturally suited to distances from 10K to the marathon, although it can also be used for shorter races and faster training sessions.

The second generation keeps the foundation of its predecessor and changes mainly the upper. In return for generous cushioning and a quick transition, it has a snug fit and a narrow heel: two characteristics that matter when assessing comfort and stability over a long race.

Specifications and weight

The midsole measures approximately 40 mm at the heel and 32 mm at the forefoot, a difference known as an 8 mm drop. That height allows for a substantial amount of foam without giving up the low weight associated with this shoe family.

One men’s reference size is quoted at around 196 grams. That figure is a guide: weight changes with size and the shoe’s configuration. Women’s versions have also been marketed with lower reference weights, but that does not mean two pairs of the same length will necessarily weigh the same.

The construction is completed by a full-length carbon-fibre plate, a lightweight mesh upper and an outsole with rubber concentrated mainly under the forefoot. These are racing-shoe choices: they reduce material where it is not considered essential and prioritise road use.

How ZoomX foam and the plate work

ZoomX is a lightweight, soft PEBA-based foam, a material used in various high-performance running shoes. It compresses under load and recovers some of its shape, contributing to the springy cushioning feel associated with the Vaporfly.

The rigid plate runs through the midsole and limits bending at the front of the shoe. Along with the curved toe, it helps the transition from landing to toe-off. It does not work in isolation: foam, plate and geometry together determine how the shoe behaves.

That does not mean the plate creates energy on its own or forces a particular landing pattern. Runners can use it whether they land on their heel or midfoot; what matters is that their landing feels comfortable and stable, without trying to change their stride artificially.

The generous cushioning is particularly relevant over longer distances, while the stiff forefoot provides a different transition from a flexible shoe. Individual response to the combination can change with speed, mechanics and fit, so a faster race time is not guaranteed.

Fit: what changed from the first Next%

The main update over the first Vaporfly Next% is the upper. VaporWeave gives way to a more flexible, breathable mesh, with a little more room at the front. The midsole retains the same general foam-and-plate formula.

The fit remains close, particularly through the midfoot. For a narrow foot, that can provide a precise hold; for a wide foot, it may mean pressure at the sides or insufficient room for the toes. Sizing up does not always solve a width issue, because it also adds length and can affect heel hold.

The laces are offset towards one side and the tongue has light padding to distribute pressure over the instep. The collar has small padded areas, although heel hold will not feel identical on every foot: excessive movement can encourage rubbing over a long race.

The most useful check is to try the pair with the socks intended for running and assess toe room, pressure at the sides and heel hold. A short fitting while standing will not necessarily reproduce the effects of heat and distance, so a run beforehand provides more useful information before racing.

Stability and foot strike

The narrow heel, midsole height and soft foam can make the shoe feel less stable than a wide-based training shoe. This may become more apparent at slower speeds, around tight turns or with accumulated fatigue, particularly if the foot moves on the platform.

There is no body weight above which this model stops working, nor a landing pattern that automatically rules it out. The decision also depends on how the foot behaves inside the shoe: a heel strike can be compatible with it, but any sense of insecurity at the rear deserves attention.

Runners who use custom orthotics should check the available space and hold with them before deciding. The original insole is glued in and the interior is snug, so adding another can reduce the available volume. If support is needed because of an injury or clinical recommendation, the professional managing the case should assess compatibility.

Distances and training sessions it suits

The combination of low weight and cushioning is particularly suited to 10K, half marathon and marathon racing. It can also be used for a 5K: the choice over a firmer or lower-profile shoe will depend on comfort and the response each runner prefers.

Outside races, it makes sense for race-pace sessions, longer intervals or a specific long run where the runner wants to understand how it behaves. Those outings allow time to check the fit and become familiar with the transition before race day, without turning every run into a gear test.

For easy runs, a training shoe can offer a more stable base and an outsole designed to accumulate miles. Alternating the two pairs also helps reserve wear on the Vaporfly for the sessions and races where its particular response is wanted.

There is no universal pace threshold a runner must beat to use a carbon plate. The shoe can also feel comfortable at moderate speeds, although its price and specialised design may carry more weight for someone who races occasionally and wants one pair for everything.

Outsole, grip and surfaces

Rubber is concentrated under the forefoot, while more foam is exposed in other areas. This layout contributes to the low weight but provides less protection against abrasion, particularly for runners who wear down the heel heavily.

Clean tarmac is its intended surface. On wet pavement, road markings, metal covers or tight turns, grip can vary; a lightweight outsole is no substitute for caution on slippery surfaces. It is not designed for technical trails or muddy terrain.

Durability: mileage and signs of wear

One broad estimate puts this generation’s useful life at around 250 to 400 kilometres, although that is neither an official limit nor a guarantee of performance. Wear changes with the surface, landing pattern and accumulated use, and some pairs may remain usable beyond that range.

Creases in the foam can appear early and do not by themselves prove that the midsole has lost its function. More meaningful signs include substantial rubber loss, lasting deformation, damage to the upper or a clear change in stability and comfort while running.

For a second-hand purchase, the actual condition matters as much as the stated mileage. Checking the outsole, heel and midsole can reveal uneven wear; heavily marked foam or a visible repair deserves careful consideration before assuming the pair has plenty of life left.

Price and buying an older version

The model was sold with a reference price of $250 in the United States. That historical figure does not establish its current price in Spain or necessarily include the sales conditions of another market. As an older generation, its cost and available sizes depend on the seller and the condition of the pair.

A discount is only an advantage if the size and fit are right. When comparing it with newer models, it is also worth checking the return policy, product description and whether the pair is new or used. With a specialised shoe, the opportunity to check the fit can be worth more than a small price difference.

Alternatives from Nike and other brands

The Nike Zoom Fly 4 also has a carbon plate, but uses React foam and is heavier, with a firmer feel and a more versatile training focus. It may appeal to runners who want a plated shoe for regular sessions, although it does not reproduce the same combination of foam and weight.

The Nike Alphafly NEXT% adds Zoom Air units in the forefoot to its foam-and-plate construction. Its platform and transition are different, so choosing between the two is not simply a matter of distance: fit and perceived stability matter too.

Outside Nike, the Saucony Endorphin Pro 2 offers another combination of lightweight foam and a carbon plate. Its upper, laces and rubber distribution are different, details that can influence the choice when two shoes share a similar racing purpose.

The legacy of a generation of racing shoes

The second-generation Vaporfly arrived in 2021, when lightweight foams and rigid plates had already changed the conversation about racing footwear. Its contribution was more evolutionary than revolutionary: it retained the first Next%’s architecture and focused the update on the upper fit.

The technological debate around this family distinguishes between running economy and the final result. Using less energy at a given speed does not translate into an identical time improvement for every runner or in every condition. That distinction helps put performance claims in context without confusing a material property with a guaranteed outcome.
