Recommended for such people
- Short distance (100m to 400m)  
- Hurdles (110mH, 400mH)  
- For those who land on their toes  
- For those who prefer a hard plate  
This is a spike for intermediate to advanced users.  
Due to the hard plate, it generates high rebound.  
For those not accustomed to track spikes, it can put a significant burden on the feet.  
It is advisable to get used to the lower-grade MIZUNO Geo Silencer FX before transitioning to Geo Sprint or Chrono Inks.  
This model has been loved for a long time by hurdle athletes, especially 110m and 100m hurdlers.  
The heel plate is a unique feature found only in this model.  
It is the perfect shoe for achieving results in competitions.  
Let's aim to update your personal best with these spikes!

Features

Similar skeleton upper to Chrono Inks

The skeleton upper achieves astonishing lightweight by leaving only the framework.  
Moreover, the lightweight yet extremely durable Dyneema material enables the skeleton structure.  
As a result, you can focus on running without worrying about the spikes shifting or breaking during sprints.  
Additionally, the fit is excellent due to the supportive belt.  
Designed with the concept of "running with a barefoot feeling," the fabric is made quite thin, making it feel almost like you're not wearing spikes at all.

Spacious design suitable for those with wider feet

The width of the spikes is particularly wide among Mizuno spikes.  
If you are an athlete with wider feet, you can wear them without worry, making them highly recommended spikes.  
Those with narrower feet can adjust the fit by tightening the laces.  
The heel is designed to be flatter compared to other spikes, giving a sensation closer to training shoes. You can feel some weight, but in return, the structure offers high cushioning.  
The toe area is rounded to avoid a cramped feeling, and the design ensures you won't get tired even after wearing them for a long time.

MIZUNO-like plate that supports stable landing

The pin configuration consists of 2-2-3-1 (outer) from the toe, totaling 8 pins, with 3 of them being fixed pins.  
The pins are evenly distributed, allowing for a firm grip on the ground while running.  
This prevents lateral movement upon landing, enabling stable running even during high-speed cornering in races.  
Additionally, the fixed pins located in the midfoot promote center of gravity movement, facilitating smooth transitions when gripping the ground.  
Overall, it is a high-performance plate that supports landing, but the large number of pins can also cause friction upon landing.  
Furthermore, the structure of the plate widens the contact area on the outer midfoot and both sides of the toe for enhanced stability.

Hurdle-compatible plate that reduces foot strain

The sole is slightly curved upwards from the ball of the foot.  
This structure makes it easier to generate speed at the optimal angle when pushing off.  
The entire contact area of the sole is made wide, making it a recommended spike for athletes who want stable footing while running or those who want to correct misalignment in the latter part of their stride.  
In terms of sole hardness, it is harder than the Geo Versus but softer than the Chrono Inks.  
The heel section features a flat plate with a jagged design for shock absorption, which also helps prevent injuries.  
It is reassuring for events like hurdles where the heel is prone to impact.  
Therefore, it is a spike that I definitely want you to try before challenging more advanced spikes.
