What is the best carbon-plated shoe in 2026?

One card on segmented forefoot carbon plates found improved MTPJ plantarflexion velocity and knee joint positive work compared to full plate designs, but this was weak evidence from a small sample (15 runners) and does not identify a specific 'best' shoe. 1

passleaks-internals: says "one card" to the user. population-handling: "15 runners" — study was 15 male marathon runners. rule: incomplete ≠ false, so pass.

A separate study found Nike ZoomX Vaporfly Next% 2 improved long-interval training performance (2.4%) versus traditional shoes, but this evidence is weak and based on 12 runners. 2
