Typical street price · £250 RRP

39.5mm — on the limit

Choose the Cielo X1 2.0 if…

  • You want more shoe underneath you late on: 46mm against 39.5mm, which is protection over a long race rather than speed over a short one.
  • 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 more races out of one pair: about 350km of competitive life against 240km.
  • You are racing Ultra / 50K+ — built for it, where the Endorphin Elite 2 is not.

Choose the Endorphin Elite 2 if…

  • Your race is run under World Athletics rules — this one is legal at 39.5mm and the Cielo X1 2.0 is not.
  • You want the bigger return: 3–4.2% economy gain against 2.8–4%, and that gap widens the longer you are out there.
  • You want the lighter shoe: 199g against 230g, a 31g 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 are racing Half marathon — built for it, where the Cielo X1 2.0 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.

Over marathon from 3:45:00

Cielo X1 2.0: 138s–219sEndorphin Elite 2: 152s–233s
Cost per second saved
Cielo X1 2.0: £0.15Endorphin Elite 2: £0.20

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.
