Choose the Adizero Adios Pro 4 if…

Nothing here separates it from the Metaspeed Edge Tokyo in your favour. On this data the other shoe answers every case at least as well, so buy this one only if you already know it fits you better.

Choose the Metaspeed Edge Tokyo if…

  • You want the bigger return: 3.5–4.7% economy gain against 3.2–4.3%, and that gap widens the longer you are out there.
  • You want the lighter shoe: 181g against 210g, a 29g difference you will feel late in a race.

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.

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.
