Thin upper made of chemical fibers resembling plastic
The upper is secured with shoelaces. It is made from a fabric that resembles woven synthetic fibers, resulting in a durable and highly fitting upper. Additionally, this fiber makes it exceptionally lightweight. Furthermore, the upper is hard and thin, which is characteristic, allowing athletes who usually wear mid-level spikes from Asics or Mizuno to experience a completely new sensation. The sturdy fabric and securely tied shoelaces prevent lateral movement, enabling you to run without worrying about your feet shifting inside the shoes during corners or high-speed races.
Thin tongue + laces tightly integrate with the foot
Being made by Asics, it has a width that is easy for Japanese people to wear. The upper material is very durable, but if you choose a size smaller than your foot, it can feel quite tight. If you have wide feet, please consider your purchase carefully. One of its features is that the tongue is quite thin, and when tied with shoelaces, it fits snugly around the entire upper. This allows for a tighter lace-up compared to regular spikes, enhancing the fit. You may initially feel some discomfort due to the thin tongue, but it poses no problem while running, so you can wear it with confidence.
Strong support for the inner weight distribution
The pin configuration consists of 7 pins from the toe: 1-2-1-3, with 3 replaceable and 7 fixed. Only 3 pins are arranged on the outer side, and compared to other spikes, the pins are positioned more towards the center, allowing for smooth weight transfer. Additionally, the fixed pins are short to minimize friction with the ground, making it very smooth to release the spikes when taking off. In contrast, due to the fewer outer pins, the support performance for preventing lateral sway during ground contact is weaker compared to other spikes. Moreover, the sole is harder compared to other spikes. The sole has almost no seams and is difficult to bend, and if you have strong muscle strength to push down, the entire sole acts as a single spring, generating high rebound.
The sole's curvature is addictive once you get used to it
The curvature of the sole is overwhelming. Due to this, the ground contact is relatively challenging and suited for advanced users. On the other hand, it provides ample support for weight transfer as it arcs from the ball of the foot to the toes. For example, if you are wearing Chrono Inks 9 but are looking for more thickness, stiffness, and curvature in the sole for a spike feel, this spike is highly recommended.
