The Vimazi Trail Z3 is designed and engineered for running on trails and rugged surfaces between 10:00-15:00 minutes per mile (6:00-9:30 min/km). With an aggressive tread, external rear stabilizer, stump-ready toe protection, and built-in forefoot control during push-off, the Z3 will take you where you want to go. When you run on trails in this pace zone, the Z3 delivers optimized cushioning and max efficiency for the way you run.

Run trails in this pace zone, and you'll always want to grab the Trail Z3. Great for 5-mile trail runs between 50-75 minutes, and amazing on 30-mile runs in the 5-8 hour range.

SIZING - True to size
 Pace-tuned Z-Foam with Forefoot FastPod
WEIGHT - 250g, 12oz (M10 US)
STACK - 31mm

AVAILABILITY: September 2023

Why they're Awesome

SPEED: Nimble and light, with an aggressive tread and stable push-off when it's time to get up and go

EFFICIENCY: A pace-tuned midsole with a forefoot FastPod deliver optimized cushioning and maximized propulsion efficiency for the pace you run when out on the trails

COMFORT: Wide toe box, molded foam heel counters, rocker design, lively pace-tuned feel, breathable upper

Trail Z3 Design Notes

RUNNER WEIGHT: The Vimazi Trail Z3 is engineered for average weight runners. 

CUSHIONING: We’ve tuned the response density of the FastPod midsoles to provide optimized cushioning for the impact forces you generate at between 10-15 minutes per mile out on the trail. Forget about "max" cushioning for some rando runner in a different pace zone—get optimal cushioning for the way you run. 

PROPULSION: We tuned the forefoot FastPods in the Trail Z3 to deliver maximally efficient energy return given the forces needed to propel you forward at this pace.

DROP: Runners at this pace are usually average weight and often midfoot to heel strikers. With this in mind, we built a 5mm drop into the Trail Z3. This helps prevent a negative heel drop angle upon impact. 

SOLE DESIGN: Rocker design and fortified arch outsole for ideal propulsion. According to the recent paper on arch compression that we wrote, forces on the arch are greatest during the push-off phase of your stride (not the impact phase). Many shoe designs carve out the arch area, exaggerating pronation. The Trail Z3 keeps the outsole area under the arch filled in to provide support during push-off, precisely when you need it most.

Why you need a pace-tuned Trail Shoe

Whenever you’re out on a trail, you want the best cushioning possible but without sacrificing push-off efficiency. You also want excellent stability on uneven terrain. That’s what you get with the Vimazi Trail Z3. We all generate a wide range of both impact forces and propulsion forces while running. Those forces are intense at 6 minutes per mile, but much less so at 14 minutes per mile, and it’s best to run in a shoe that responds to the forces you’re generating rather than the forces someone else is generating. Common sense! So if you’re averaging 10-15 min/mile out on the trails, the Trail Z3 is your shoe.

At Vimazi, we carefully studied midsole material and how it responds to running forces. We found that it’s not possible for one midsole foam to respond correctly to all paces. What does this mean? Midsole densities need to be adjusted to the speed of the runner. (Kind of a problem for all those running shoe brands that try to sell every shoe to every runner, irrespective of pace.) It’s time to ditch those generic clone shoes.

Our research also showed that the propulsion forces in your forefoot and toe are greater than the impact force you encounter in the midfoot and heel. As a result, running shoes need to be tuned by both pace and between heel and forefoot, at least if you want the best performing shoe. 

By adjusting midsole density in the heel and midfoot to the forces you generate at 10-15 minutes per mile, you get the precise amount of cushioning you need at that pace. Goldilocks cushioning for the trails you run. Pace-tuned cushioning in the Vimazi Trail Z3 ensures the comfort and health benefits that come with reduced shock.

But you’d never want better cushioning to get in the way of a propulsive push-off. To get the energetic push-off you want, the forefoot of your shoe should be tuned differently than the heel. We’ve engineered the forefoot FastPod in the Trail Z3 so that it specifically responds to the propulsion force you generate between 10-15 minutes per mile. Improved stability is the added trail running benefit with a pace-tuned forefoot because when your foot hits the ground, most of the time is spent on the push-off phase.

The result: The Trail Z3 reduces shock while increasing efficiency and stability when running on trails between 10-15 minutes per mile (6:00-9:30 minutes per kilometer).
