Nike Vaporfly 4 Review: The Ultimate Carbon Racing Shoe for Triathletes

What to Look For

A carbon plate racing shoe can make a measurable difference to your run split in triathlon — particularly at sprint and Olympic distances where seconds count. The Nike Vaporfly 4, released in March 2025, builds on one of the most successful race shoe lineages in history with a lighter build, updated ZoomX foam and improved stability. Here is what to look for when choosing a carbon race shoe, and why the Vaporfly 4 earns top marks.

Key Features to Consider

  • Carbon plate — the Flyplate provides propulsive energy return, reducing the muscular effort required to maintain pace; key for the run leg after swim and bike
  • ZoomX foam midsole — Nike’s lightest and most responsive compound, with exceptional energy return for faster leg turnover
  • Weight — the Vaporfly 4 comes in at approximately 165g for a men’s UK 8, making it one of the lightest carbon shoes on the market
  • Drop and stack — 6mm heel-to-toe drop (reduced from the Vaporfly 3) provides a more natural running posture; suits midfoot and forefoot strikers

Our Top Picks

Best Overall: Nike Vaporfly 4 (Men’s)

The Vaporfly 4 is the evolution the series needed. Lighter than the Vaporfly 3, more stable and with an improved ZoomX midsole that delivers noticeably snappier energy return, this shoe suits 5K through to marathon pace. The new woven mesh upper is breathable, lightweight and does not retain water — an important quality for triathlon run legs that may start in wet kit. Released March 2025 at £210.

Best for Women: Nike Vaporfly 4 (Women’s)

The women’s Vaporfly 4 shares the same ZoomX foam and Flyplate carbon construction as the men’s model, retuned for female biomechanics with a slightly narrower heel fit. Available from £162 across UK retailers, it offers the same race-day performance at a potentially lower entry price depending on colourway availability.

Best Alternative: ASICS Metaspeed Sky Paris

If Nike’s fit does not work for you, the ASICS Metaspeed Sky Paris is the closest rival in the carbon shoe market. Optimised for stride-length runners with its 6mm drop and FF Turbo Plus foam, it offers comparable energy return to the Vaporfly 4 at similar price points. A genuinely competitive alternative for long-distance events.

Buying Tips

  • The Vaporfly 4 fits true to size but has a snug racing fit — if you are between sizes, go half a size up
  • Reserve carbon shoes for race day and key interval sessions only; wearing them daily significantly reduces the foam’s responsiveness
  • Look for previous colourways of the Vaporfly 3 at 30–40% discount now that the 4 is available — excellent value for threshold training

Care and Maintenance

Wipe the midsole clean after each use and allow to air dry naturally — never machine wash or tumble dry carbon shoes as heat degrades the foam compounds. Store in a cool, dry place away from direct sunlight. With proper care and limited use (race days and threshold sessions only), a pair of Vaporfly 4s should last 400–500km.
