Choose the Adizero Adios Pro 4 if…

  • You want the bigger return: 3.2–4.3% economy gain against 2.6–3.6%, and that gap widens the longer you are out there.
  • You want more shoe underneath you late on: 39mm against 33mm, which is protection over a long race rather than speed over a short one.
  • You want a conventional fit rather than a narrow or wide last.
  • You are racing Half marathon or Marathon — built for it, where the FuelCell SuperComp Pacer v3 is not.
  • You would rather buy on measured numbers: this shoe's specs are manufacturer-confirmed, the FuelCell SuperComp Pacer v3's are estimated.

Choose the FuelCell SuperComp Pacer v3 if…

  • You want the lighter shoe: 170g against 210g, a 40g difference you will feel late in a race.
  • You have a broad foot, or your toes spread as a long race goes on.
  • Money matters: it is selling around £118 against £176, and the time difference between them is smaller than the price difference suggests.
  • You are racing 5K — built for it, where the Adizero Adios Pro 4 is not.

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.
