A stress-free upper that feels like running barefoot
The upper features a very pleasant HL-0 mesh that feels silky, providing an excellent fit without stress. It has a softness reminiscent of a celestial maiden's garment. The inner texture is similar to that used in the upper of NIKE's Zoom Mamba V and Matumbo 3. Overall, it is quite thin and very light, creating the first impression. As a result, it feels almost as if you are running barefoot, with hardly any sensation of wearing spikes. This was surprising. The laces are of a stretchable type, ensuring a secure hold without gaps according to the tied sections, providing peace of mind. It is very troublesome if the laces come undone while running long distances, so having laces like those of the COSMORACER LD2 that are easy to secure is reassuring.
A flexible upper that can be worn even by those with wider feet
The upper is soft, allowing even those with wider feet to wear it comfortably. Conversely, for those with narrower feet, tightening the laces ensures a snug fit, creating a relatively flexible width that prevents any movement inside.
A soft sole with grip unique to rubber that can grasp the ground
▶ Pins The pins are fixed 4mm with 5 pieces. (Base 2mm + pin 2mm for a total of 4mm) Compared to other long-distance spikes, they are shorter, resulting in less resistance during takeoff, providing a feel similar to marathon shoes. ▶ Sole Shape The sole surface employs a semi-transparent rubber made of urethane, firmly gripping the ground. Additionally, the honeycomb structure allows for a larger surface area to contact the ground. Partially, there is a responsive Pevax (the black part inside the rubber), but since it's only a part, its contribution to responsiveness is low. ▶ Sole Hardness The sole is very soft, boasting the best flexibility among all long-distance spikes. However, the forefoot has elasticity, allowing it to return during takeoff, supporting propulsion and enabling smooth movement.
Flat-shaped sole with no incline
The curvature of the sole is among the smallest in long-distance spikes, ranking second alongside NIKE's Zoom Victory Elite 2, providing a comfortable fit without peculiarities, making it quite easy for beginners to wear. Additionally, the midsole uses a lightweight yet highly cushioned material called FLYTEFORM. This midsole is a unique sponge material developed and patented by ASICS, which is 55% lighter than the conventional midsole material E.V.A used by ASICS, while providing cushioning and durability.
