RUNNING SHOES, PERSONALIZED

We’re footwear veterans and lifelong runners. Like you, we know how good it feels to run with more energy. So we set out to make running shoes that feel lively underfoot, propel us forward, and provide optimal cushioning. The journey led us to something that's never been done before. Pace-tuned running shoes.

We understand the power of pace

Scott Tucker is constantly working to trim minutes off his marathon time. So it’s not surprising that during a 6am interval workout in 2017, he had a brainstorm—shoes tuned to specific pace zones should respond more efficiently to the forces generated in running than non-tuned shoes. With a team of scientists, Scott conducted a research study that proved the theory. He also discovered that tuning shoes by pace resulted in optimized cushioning.

With solid data and a patent pending on the tech, Scott grabbed his high school running buddy John Zilly, a marathoner himself, and together they formed Vimazi. Right at the inception they committed to championing the spirit of running for all runners. They’ve done that by pursuing the scientific truth about running forces and footwear, wherever it leads. They also champion runners by personalizing shoes according to pace. So every runner gets the shoe they need to feel their best.

It’s important to know that the word “Vimazi” isn’t random. It comes from Greek roots meaning “pace zone.” Our flying V logo is inspired by the italic V with a line over it that stands for velocity in physics equations. We have a lot of fun running, but we take the math and physics that back up our technology seriously. That process forced us to relearn everything we thought we knew about running shoes. As we launch our first shoes in 2022, we’re ready to share that rethinking with runners like you, because a lively run is a better run. Plus, nabbing a PB is always nice. Get ready for a revolution.

Frequently asked questions

Why do I need a pace-tuned shoe?

We conducted a Forces in Running study which looked at the timing, location, and intensity of forces generated while running. The research included a variety of paces and footstrike patterns. Based on the study, we know the exact forces generated at different paces in the heel, arch, forefoot, and big toe. 

Two key findings: One, while running, we generate a dramatic range of both impact forces and propulsion forces. Those forces are intense at 5 minutes per mile (3:06 min/km), less so at 8 minutes per mile (5:00 min/km), and even more gentle at 12 minutes per mile (7:27 min/km). Two, the impact force at any given pace is much different than the push-off force. 


We also found that midsole foam (it doesn’t matter what type) isn’t nearly as adaptable as we’ve all been led to believe by running shoe brands. In fact, it’s physically impossible for one midsole foam to respond appropriately at all running speeds. Your midsole might be way too soft and inefficient or way too hard and devoid of proper cushioning. If you want a midsole that responds correctly to the pace you run, the foam density needs to be adjusted to address the forces at that pace. We call that density adjustment “tuning.”

All this means two fundamental things. First, the heel and midfoot need to be tuned differently from the forefoot to accommodate the differing forces. Second, midsole foam needs to be tuned for specific pace zones in order to respond appropriately.

By tuning midsole foam density between heel and forefoot and by pace zone for each of our models, we’re able to optimize cushioning and maximize push-off efficiency for every runner. The only way to get the best cushioning and the most energy out of your shoes is if they’re tuned for the pace you run.

How do I know pace-tuned shoes work?

The data from our Forces in Running study clearly shows that when tuned correctly, pace-tuned shoes give you optimized cushioning and maximized propulsion efficiency. Vimazi CEO Scott Tucker published three research papers using our study data, and we have a patent pending on the technology.

How do I decide which pace zone?

What’s your pace range for the majority of miles you run? Use that range to select your first pair of Vimazi pace-tuned shoes. If you love them, you may want to add a second pair that works for an adjacent pace zone.

Here's an alternative way to think about it. If you have an upcoming event and really want to rock your pace zone, then you could select the model that works best for your target race pace.

What's the fit like? Do they come in different widths?

We’re a small startup and don’t have the resources to produce multiple shoe variations. That said, the fit of our shoes is superb. We’ve spent years perfecting footwear fit at other brands. Plus, we're life-long runners, so we know how important fit is for running shoes. The snug heel and wide toe box of our shoes should feel great for the majority of runners. Also, the fit is the same for each of our models, so if one works for you then another model will give you the same fit.

What’s taking so long?

For many, many reasons there are lots of pressures on shoe suppliers and their partners right now. As a small startup, we’ve unfortunately been pushed to the back of the line a few times. Additionally, covid has fouled up supply chains worldwide, including footwear. Most importantly, however, we’re not going to churn out shoes to make quick sales. We love running and we know you love running, so we’re going to release the shoes when they’re awesome, and not before.

Are there any color options?

We know you want to express yourself to the world, so we definitely plan to offer color options for each of our shoes. For 2022 and 2023, however, there will only be one color available for each model. That's the way it goes with a startup. We'll get the color wheel out after we get a little bigger.
