WHY IT’S AWESOME

SPEED: Insanely light 1-ply upper, Strategic rubber, Speed platform

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

COMFORT: Wide toe box, contoured heel pocket, lively pace-tuned feel

Z30 DESIGN NOTES

ENGINEERING SPECS: Average adult ranges for height, cadence, and body weight at this pace.

CUSHIONING: At this pace, when your stride's flight distance is the greatest, you generate a lot of force on impact, so we’ve tuned the reaction density in the heel to provide optimized cushioning for the forces you create. Forget about "max" cushioning for some rando runner—get optimal cushioning for the way you're running today.

PROPULSION: It takes a lot of force to push off hard enough to travel 16-25 feet through the air, so the last thing you want is a soft, inefficient midsole. We’ve tuned the forefoot FastPod in the Z30 to deliver maximally efficient energy return given the forces you generate at this pace.

DROP: Runners at this pace are usually lightweight and often forefoot strikers. With this in mind, we built in a 4mm drop into the Z30. It’s ideal for fast, flexible, midfoot, and forefoot runners because it provides the most natural biomechanics while preventing a negative drop angle upon impact.

SOLE DESIGN: Rocker design and fortified arch outsole for ideal propulsion. According to a 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 Z30 fills the arch area to provide support precisely when you need it most.

MIDSOLE MATERIAL: Vimazi Z-Foam has an EVA (ethylene vinyl acetate) base. Proprietary additives have been mixed into the EVA to increase abrasion resistance and elongation properties. Most importantly, however, we use our specific EVA blend because it allows us to dial in an ideal compression set for each model. This isn’t possible using other common midsole foams. Finding a foam matrix that could be specced to specific durometers was one of the reasons it took five years to develop and produce our pace-tuned shoes. Our midsole formulas are the heart of the technology. They’re what allow us to tune the Vimazi Z30 to a peak force spec of 840N in heel/midfoot and 1120N in forefoot (W11.5). No one else does this, and you can't tune shoes in this way using other midsole foams.
