Choose the Metaspeed Edge Tokyo if…

  • You want the bigger return: 3.5–4.7% economy gain against 3–4.2%, and that gap widens the longer you are out there.
  • You want a conventional fit rather than a narrow or wide last.
  • You are racing 10K — built for it, where the Cloudboom Strike is not.
  • You would rather buy on measured numbers: this shoe's specs are manufacturer-confirmed, the Cloudboom Strike's are estimated.

Choose the Cloudboom Strike if…

  • You have a narrow foot and want to be locked in.

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–266sCloudboom Strike: 152s–233s
Cost per second saved
Metaspeed Edge Tokyo: £0.22Cloudboom Strike: £0.23

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.
