Choose the Metaspeed Edge Tokyo if…

  • You want the bigger return: 3.5–4.7% economy gain against 2.7–3.8%, and that gap widens the longer you are out there.
  • You want the lighter shoe: 181g against 217g, a 36g difference you will feel late in a race.
  • You race off a strong, repeatable stride and want the more aggressive ride rather than the safer one.

Choose the Endorphin Pro 4 if…

  • You want something more forgiving. This is the steadier platform — useful if your form goes late, or if you are on your feet longer.
  • Money matters: it is selling around £120 against £200, and the time difference between them is smaller than the price difference suggests.
  • You want more races out of one pair: about 350km of competitive life against 250km.

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.

Metaspeed Edge Tokyo: £0.22Endorphin Pro 4: £0.13

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.
