Choose the Metaspeed Edge Tokyo if…

  • You want the bigger return: 3.5–4.7% economy gain against 3.2–4.4%, and that gap widens the longer you are out there.
  • You want more shoe underneath you late on: 39.5mm against 35mm, which is protection over a long race rather than speed over a short one.

Choose the Vaporfly 4 if…

  • Money matters: it is selling around £120 against £200, and the time difference between them is smaller than the price difference suggests.
  • You are racing 5K — built for it, where the Metaspeed Edge Tokyo is not.

What does this
mean for you?

Every figure below is recalculated from your race and your current time. The gap between two shoes is not fixed — it grows with how long you are on your feet.

Over marathon from 3:45:00

Time back
Metaspeed Edge Tokyo: 186s–266sVaporfly 4: 165s–246s
Cost per second saved
Metaspeed Edge Tokyo: £0.22Vaporfly 4: £0.15

Ranges, not promises. Both figures are against a standard trainer, and the honest answer for most runners is that the difference between two shoes of this class is smaller than the difference a month of decent training makes.

Every number.

Best use case
Metaspeed Edge TokyoThe cadence runner’s version of the Sky. Higher drop, more aggressive roll, same foam and plate package.
Vaporfly 4The most versatile super shoe on sale. Light enough for a 5K, cushioned enough for a marathon, and the fourth generation fixed the upper problems that made the VF3 divisive.
