Choose the Alphafly 3 if…

  • Money matters: it is selling around £203 against £300, and the time difference between them is smaller than the price difference suggests.

Choose the Endorphin Elite 3 if…

  • You want the lighter shoe: 190g against 218g, a 28g difference you will feel late in a race.
  • You are racing 10K — built for it, where the Alphafly 3 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

Time back
Alphafly 3: 179s–260sEndorphin Elite 3: 172s–253s
Cost per second saved
Alphafly 3: £0.23Endorphin Elite 3: £0.37

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
Alphafly 3Still the reference marathon shoe. The Air pods give a propulsive forefoot that nothing else quite replicates, and the wider platform makes it manageable late in a race when your form has gone.
Endorphin Elite 3The softest ride at this level by some distance, and the third generation finally made it serious rather than just fun. A genuine top-tier option.
