Nike Vaporfly 4% (NIKE), lightweight racing flats (FLAT) and their habitual footwear (OWN).

1️⃣8️⃣ male recreational runners 🏃🏻‍♂️

Running Economy was improved in NIKE (3.6 to 4.5%, p ≤ 0.002) and FLAT (2.4 to 4.0%, p ≤ 0.042) versus OWN across intensities, with a trivial difference between NIKE and FLAT.

➡️ Only 29% of runners were more economical across intensities and faster in NIKE.

➡️ NIKE could benefit Running Economy in male recreational runners at relative speeds when compared to OWN, but not when compared to FLAT.

➡️ More runners exhibited better Time Trial performances in NIKE (61%) versus FLAT (22%) and OWN (17%).

🆕 The high variability in individual RE (-3.1 to 12.1%) and TT (-3.8 to 8.2%) shoe-responses suggests that individualisation of running footwear prescription is warranted.
