Nike Vaporfly 4 vs Saucony Endorphin Pro 5:
Which to Choose

These two are genuinely close, so the differences that exist matter. The clearest gap is weight: the Vaporfly 4 comes in around 166–167g in a men's sample, while the Endorphin Pro 5 sits closer to 215g — a real, noticeable margin that makes the Nike feel more overtly featherweight underfoot and helps explain why it's often pitched as the purer 10K-to-half specialist. Drop is effectively a wash: roughly 8mm on the Vaporfly and 9mm on the Endorphin (Saucony markets it as 8mm), so neither will feel meaningfully more heel- or forefoot-biased than the other. The bigger character difference is in the midsole. Nike keeps it simple with a single slab of soft, lively ZoomX PEBA over a full-length carbon Flyplate, giving a plush-yet-springy, forward-tipping roll that comes alive at your fastest sustainable efforts. Saucony runs a dual-foam stack — a PWRRUN PB (PEBA) top layer over a supercritical PWRRUN HG base — paired with a forked, slotted full-length carbon plate, which reads as a touch firmer and more aggressively rockered, snapping you onto the toes with real urgency. Both share the same racing DNA: tall, narrow, low-stability neutral platforms that feel tippy and vague at jog pace and only make sense when you're pushing. Where they diverge is the sweet spot — the Vaporfly is most efficient in the 10K-to-half band, while the Endorphin's rocker feels most effortless over the half and full — but both are fully capable across all four distances.
