Choose the Adizero Takumi Sen 11 if…

  • You want the lighter shoe: 160g against 217g, a 57g 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.
  • You have a narrow foot and want to be locked in.
  • Money matters: it is selling around £95 against £120, and the time difference between them is smaller than the price difference suggests.
  • You are racing 5K — built for it, where the Endorphin Pro 4 is not.

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.
  • You want a conventional fit rather than a narrow or wide last.
  • You want more races out of one pair: about 350km of competitive life against 250km.
  • You are racing Half marathon or Marathon — built for it, where the Adizero Takumi Sen 11 is not.
  • You would rather buy on measured numbers: this shoe's specs are manufacturer-confirmed, the Adizero Takumi Sen 11's are estimated.

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.

Best use case
Adizero Takumi Sen 11A short-distance specialist with real carbon underneath. Firm, aggressive and brilliant for 5K and 10K where a marathon shoe feels like too much.
Endorphin Pro 4The stable, sane super shoe. Lower stack, wider base, far less demanding than the flagships and much longer lasting.
