The Vimazi Trail Z2 is designed and engineered for running on trails and soft surfaces between 8:00-12:00 minutes per mile (5:00-7:30 min/km). With an aggressive tread, external rear stabilizer, stump-ready toe protection, and built-in forefoot control during push-off, the Z2 will take you where you want to go. When you run on trails in this pace zone, the Z2 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 Z2. Great for 5-mile trail runs between 40-60 minutes, and amazing on 30-mile runs in the 4-6 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 Z2 Design Notes

RUNNER WEIGHT: The Vimazi Trail Z2 is engineered for average weight runners. 

CUSHIONING: We’ve adjusted the density of the FastPod midsoles to provide optimized cushioning for the impact forces you generate between 8-12 minutes per mile (5:00-7:30 min/km) 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 Z2 to deliver maximally efficient energy return given the forces needed to propel you forward at this pace.

DROP: We built a 5mm drop into the Trail Z2 to reduce the chance of a negative heel angle during impact. 

SOLE DESIGN: Rocker design and fortified arch outsole for ideal propulsion. According to our recent paper on arch compression, 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 Z2 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 Z2. We all generate 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. 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!

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 8-12 minutes per mile (5:00-7:30 min/km), 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 Z2 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 Z2 so that it specifically responds to the propulsion force you generate between 8-12 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 Z2 reduces shock while increasing efficiency and stability when running on trails between 8-12 minutes per mile (5:00-7:30 minutes per kilometer).
