Choose the Streakfly 2 if…

  • You have a narrow foot and want to be locked in.

Choose the Deviate Nitro Elite 3 if…

  • You want the bigger return: 2.9–4% economy gain against 1.8–2.9%, and that gap widens the longer you are out there.
  • You want more shoe underneath you late on: 38mm against 32mm, 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 Streakfly 2 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.

Best use case
Streakfly 2A proper short-distance racer for people who find full super shoes unwieldy at 5K pace. Lower, firmer, more connected to the ground.
Deviate Nitro Elite 3The sane sibling to the Fast-R. Light, versatile, considerably cheaper, and easily the most underrated racer here.
