Z40 Beta
The Vimazi Z40 is specifically tuned and designed for running between 6:15-7:45 minutes per mile (3:55-4:45 min/km). Optimized for quickness and max energy efficiency at pace. Slightly wider platform for enhanced stability at speed. For workouts and races in this pace zone, this is the shoe you need to run your best.

Who It’s For
If some of your training runs are within this zone, the Z40 is your shoe. For racing, if you’re running 10ks between 38:50-48:00 or marathons in the 2:45-3:24 range, it’s the perfect shoe. Best for fast long runs, tempo runs, intervals and fartleks, racing.

z40 Design Notes

RUNNER WEIGHT: The Vimazi Z40 is engineered for slender to average weight runners. 

CUSHIONING: At this pace, the long flight distance for each stride creates a lot of force, so we’ve tuned the response density of the FastPod midsoles 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: At this pace it takes a lot of force to propel yourself forward, so the last thing you want is a squishy, inefficient midsole. We’ve tuned the forefoot FastPods in the Z40 to deliver maximally efficient energy return given the forces at this pace.

DROP INFO: Runners at this pace are usually light in weight and often midfoot strikers. With this in mind, we built a 5mm drop into the Z40. This helps prevent a negative heel 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 during the propulsion phase of your stride. The Z40 fills the arch area to provide support during push-off, precisely when you need it most.
