What Are Pace Zones?

What Are Pace Zones?

For Vimazi, pace zones are the ideal pace ranges for each of our shoe models. Let’s use the Vimazi Z60 as an example. The Z60 performs best between 8:30-10:30 min/mile (5:15-6:30 min/km). We’ve tuned the heel area of the midsole so it responds correctly to the forces in that pace range. What does that mean? If you’re running within that pace zone, the heel FastPod offers perfect cushioning. It’s not so soft that you’re unstable and bottoming out, and it’s not so hard as to strain your joints and soft tissues. If you ran 5:00 min/mile in the Z60, it would act like other shoes on the market and would be too soft to give you efficient, Goldilocks cushioning. If you ran 13 min/mile, it wouldn’t maximize your cushioning. We want your cushioning to be just right.

 

Similarly, the forefoot FastPod in the Z60 is tuned to give you maximum propulsion efficiency within its pace zone — 8:30-10:30 min/mile. How does propulsion efficiency work? If your midsole is too soft for the propulsion forces you generate at the pace you’re running, you’ll compress it and get nothing back. Kind of like running in sand. And that’s what you get with most shoes today. During the push off phase of your stride, the Z60 forefoot FastPod compresses but doesn't bottom out then quickly rebounds back into place. This is the only way to get the most efficiency out of your propulsion effort.

 

But why doesn’t one shoe work for all paces? Turns out the the forces in running change dramatically as you increase pace. That’s because the faster you run, the farther you fly through the air. A longer flight means much greater impact when you land and much greater effort and force required when you push off. Here’s what happens with one shoe: At a very fast pace the midsole might act like running on memory foam while the same midsole at a slower pace may be too hard and jarring. By running in shoes properly tuned to your pace zone, you’ll feel better and run faster over distance.
