At a recent overseas road race, a pure-white Nike prototype drew particular attention. It is very likely the next-generation Vaporfly 5. But based on the content circulating on social media so far, there appear to be three leaked versions of what could be the Vaporfly 5. The pure-black leaked version was the first. The upper uses the same fine engineered knit as the Vaporfly 4. The biggest changes are in the midsole. It adopts an almost exaggerated forefoot-rearfoot split design, with only a very narrow foam connection at the midfoot. Judging by the foam texture, it is very likely still a ZOOMX midsole made from PEBA material currently on the market. With the midfoot so "hollow", weight savings are achieved, and it can better guide runners to use forefoot stack height and carbon-plate stiffness to accelerate. But for rear- or midfoot-strike runners, could gait-guidance issues be a concern? The outsole greatly reduces heel rubber coverage and shifts that rubber more medially, while the forefoot rubber receives a dotted perforation treatment. Would over-pronating runners cause the foam to wear more quickly with this design? Recently, a video from an overseas road race revealed a second version suspected to be the Vaporfly 5. Aside from major upper changes, the overall shoe structure appears unchanged. The new coarse-mesh knit upper has more cutouts than the black version, so it should be superior in weight and breathability compared with the earlier lateral knit. Thinner laces also contribute to weight savings. If you look closely, the second version's crease depth is shallower than the first—does this indicate the foam has been tuned? Has it become more resilient or springy? Spy shots of a third version have surfaced recently. Compared with the first two, this one leans fully toward an "aggressive" direction and even seems to abandon the Vaporfly 4's previous design philosophy. The upper, like the second version, is a coarse mesh knit and uses a heat-pressed, Flywire-like technology on the upper to enhance midfoot lockdown. The midsole appears to have a completely different texture from current ZOOMX, so it's possible Nike is using a new midsole material. Additionally, the third version's midsole is much thinner than the first two, becoming a true forefoot-rearfoot split midsole and making it more "elite-focused." Its forefoot rocker/roll height is among the highest in current Nike running products. These structural designs bring immediate improvements in push-off efficiency. Does this remind you of a particular shoe? One that also features forefoot-rearfoot separation and pursues extreme push-off performance—a top-tier carbon racing shoe? What do you think the Vaporfly 5 from Nike will ultimately look like in terms of style and approach?
