Choose the Metaspeed Edge Tokyo if…

  • You want the bigger return: 3.5–4.7% economy gain against 2.9–4%, and that gap widens the longer you are out there.
  • You want the lighter shoe: 181g against 200g, a 19g difference you will feel late in a race.
  • You would rather buy on measured numbers: this shoe's specs are manufacturer-confirmed, the Rocket X 3's are estimated.

Choose the Rocket X 3 if…

  • Money matters: it is selling around £140 against £200, and the time difference between them is smaller than the price difference suggests.

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–266sRocket X 3: 145s–219s
Cost per second saved
Metaspeed Edge Tokyo: £0.22Rocket X 3: £0.17

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.
