Choose the Metaspeed Sky 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 something more forgiving. This is the steadier platform — useful if your form goes late, or if you are on your feet longer.
  • You want a conventional fit rather than a narrow or wide last.
  • You are racing 10K — built for it, where the Wave Rebellion Pro 4 is not.
  • You would rather buy on measured numbers: this shoe's specs are manufacturer-confirmed, the Wave Rebellion Pro 4's are estimated.

Choose the Wave Rebellion Pro 4 if…

  • You race off a strong, repeatable stride and want the more aggressive ride rather than the safer one.
  • You have a narrow foot and want to be locked in.
  • Money matters: it is selling around £125 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.

Cost per second saved
Metaspeed Sky Tokyo: £0.22Wave Rebellion Pro 4: £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.

Best use case
Metaspeed Sky TokyoFor stride-length runners — the Sky is built to let your stride open up rather than turn over faster. Arguably the best all-round marathon shoe currently made.
Wave Rebellion Pro 4The cut-away heel forces you onto your forefoot whether you meant to or not. Divisive, distinctive, and fast if it suits you.
