Very distinctive Flyweave upper
The features of this spike are "number of pins," "lightness," and "sole stiffness." The upper is made of a lightweight and soft synthetic material called Flyweave Upper. It provides a high level of fit that gently wraps around the entire foot. When hearing about a soft upper, one might think that the hold is weak, leading to foot slippage within the spike upon landing. However, this Flyweave Upper maintains softness while firmly securing the top of the foot as if it were molded by wires. Therefore, the hold is not lost at all, and there is almost no instability upon landing. Additionally, it boasts high durability suitable for 400m.
Outstanding hold and narrow overseas specifications
This spike offers a high level of hold and fit, making it very comfortable to wear; however, please note that it is designed specifically for athletes with narrower feet. A characteristic of Nike products in general is the "narrowness of the foot width" and "low instep" compared to spikes made by Japanese manufacturers. This spike shares similar characteristics, which means that the number of "wearable athletes" is somewhat limited. Due to this feature, both the upper and sole are designed to be slim. If your foot does not sit firmly on this slim sole, the instability upon landing will inevitably increase. Therefore, athletes with wider feet may find it difficult to feel the hold.
Easy-to-use plate for short distances compatible with 400m
The pins are arranged in three rows with seven pins, which is one less than Fly Elite and JA Fly, resulting in less deceleration due to friction. The plate is slightly softer compared to the aforementioned two pairs, making the Zoom 400 recommended for those who find these two pairs too hard. Additionally, the inclusion of a midsole features a balance between softness and high resilience. The reduction of load due to this midsole allows for the maintenance of top speed for a longer duration, which is crucial for 400m. The honeycomb structure also contributes to a plate that is not just stiff. Furthermore, the narrow arch characteristic of Nike may cause athletes with wider feet to feel that their feet do not fully fit on the plate, potentially leading to some instability upon landing.
A flat and easy-to-run sole for NIKE
The toe is high and curved, but compared to other Nike models, the incline is lower. It rises from under the ball of the big toe, allowing the arch to engage with the ground, which helps utilize the flexibility of the sole. Since the sole itself bends well, if you can kick through to the end, you can receive a rebound greater than the stiffness of the sole.
