Jet Sprint Evaluation Review

¥25,300(including tax)

Hard high-rebound plate

It has an explosive rebound force that feels like being bounced back the moment you make contact with the ground.

Seamless upper with excellent stability and fit

It fits the foot with high fit and provides stability.

Flat-type sole adopting a flat concept

The sole has been designed with almost no incline to minimize the contact time with the ground.

Ground feel that does not interfere with running, featuring six pins

Reduces friction and braking upon landing, allowing for a smooth foot release.

Recommended for such people

- 100m athletes  
- Athletes skilled at landing flat and receiving rebound  
- Athletes with stable landings that do not escape outward  
This popular spike requires a specific running type and technique. Although it is the spike that Kiryu used to achieve a sub-10 second time, actual statistics show that it is considerably less common compared to Chrono Inks or Zoom Superfly Elite.  
The low number of wearers indicates the difficulty in handling the spike. The sole, which has almost no characteristic incline, is designed to minimize landing time but does not assist in the push-off at all. Therefore, it is recommended for those with a flat running style who can effectively receive rebound!

Features

Upper designed to challenge weight reduction

The upper is made of synthetic fiber/synthetic resin/artificial leather and is seamless with no stitches.  
This allows for a high level of fit that wraps around the entire upper, providing a secure fit and stability for the foot.  
The material used, HL-0 MESH, is thin yet very durable and lightweight. You can experience a smooth sensation of your foot moving forward.  
This HL-0 MESH is a soft and well-fitting material that achieves a fit that wraps around the foot, resolving the poor fit that was a drawback of traditional Asics.  
However, since the fabric is very thin, it is prone to damage, so it is not recommended for heavy use in both competition and practice.

Perfect fit that covers the entire instep

The upper is generally made to be tight (slightly narrower), achieving a high level of fit.  
The toe area has ample width, so although it is overall tight, it is unlikely to cause cramping or toenail issues.  
Athletes concerned about foot width should try a size 0.5 cm larger than usual.  

The shape of the heel is slightly narrower, but it is not as narrow as overseas spikes, making blisters less likely to occur.

Minimal yet highly functional sole

The pins consist of a total of 6, with 2-1 (inner side)-3 from the toe.  
It features a simple one-piece plate. Therefore, it is a spike that users have clear preferences for.  
Compared to other spikes, it is quite stiff and difficult to bend, achieving high rebound.  
Users need advanced technique to bounce upon landing rather than firmly pressing down after landing.  
Additionally, the fewer pins and the shorter 5mm pins compared to other spikes reduce friction and braking upon landing. This results in a smoother foot release during takeoff.  
Overall, it is a plate suitable for athletes who have established their running technique at an advanced level.

Ultra-flat. A sole that has changed short-distance spikes

There is almost no curvature in the sole. When compared to Chrono Inks, the difference is clearly noticeable. Normally, spikes with an angle support the action of pushing down near the tip of the foot, but this spike lacks an angle, requiring advanced technique to bounce before pressing down rather than pressing down after landing.
