New Balance FuelCell SuperComp Trainer v4vs
Saucony Kinvara Pro
Choose the FuelCell SuperComp Trainer v4 if…
- You want the bigger return: 2.4–3.5% 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: 47mm against 42mm, which is protection over a long race rather than speed over a short one.
- You race off a strong, repeatable stride and want the more aggressive ride rather than the safer one.
- You have a broad foot, or your toes spread as a long race goes on.
- You want more races out of one pair: about 650km of competitive life against 600km.
- You are racing Ultra / 50K+ — built for it, where the Kinvara Pro is not.
Choose the Kinvara Pro 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.
- Money matters: it is selling around £99 against £157, and the time difference between them is smaller than the price difference suggests.
- You are racing Half marathon — built for it, where the FuelCell SuperComp Trainer v4 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
- FuelCell SuperComp Trainer v4: 111s–186sKinvara Pro: 69s–145s
- Cost per second saved
- FuelCell SuperComp Trainer v4: £0.10Kinvara Pro: £0.10
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.

List price. Almost nobody pays it for a race shoe.
Street price divided by the races the foam stays fast for.
The whole-life question: what each second of race time costs you.

Neither is better in the abstract — it depends on your stride.
How long the foam stays fast, not how long the shoe survives.
■ marks the better figure where one is genuinely better. Fit, foam, drop and stability carry no mark — they depend on your foot and your stride, not on which shoe is superior.
