Resolution of the tear-prone upper issue from models prior to 2020
The material has been changed from the 2020 model to a CELERMESH that is woven in a lattice pattern. It excels in breathability, lightweight, flexibility, and stability compared to the previous model. The material is so thin that you can see your fingers through it, making it feel soft. The following two points are evaluation points regarding stability: - Tear-resistant - Feet do not move easily inside the spikes The laces have been changed to a more fitting material, with slight improvements regarding the stretchability issues that were common with Adidas laces. Those who want to tighten their shoelaces can now feel a good fit without any issues. If you prefer to choose middle-distance spikes based on upper stability, we recommend the COSMORACER MD2 for better stability.
Slim and elongated fit
We recommend a fit that is about 0.5 cm smaller than your usual size. While it is positioned as slightly narrow in terms of foot width, there are no particularly narrow areas from the heel to the toe, and the upper is not stiff, so those with wider feet will also find it a suitable size. It is narrower than Asics' COSMORACER MD2 and Mizuno's Geosplash 7, but about the same width as Nike's Zoom Victory Elite 2 and Zoom 400. Additionally, since the impact of ground contact is emphasized more than other middle-distance spikes, the heel is supported with slightly thicker material for stability.
Sole with sprint-level high rebound
◆ About the pins There are 5 pins, which is fewer compared to other manufacturers' middle-distance spikes. (For reference: NIKE Mamba V, MIZUNO Geosplash 7: 6 pins) A notable feature of the sole is that two pins are arranged closer to the inside of the toe. This has led to many reviews stating that it is well-suited for forefoot running styles, where the center of gravity shifts towards the inside of the toe when taking off. ◆ About the sole Among middle-distance spikes, it is quite hard and has high rebound suitable for short-distance events like the 400m. Generally, the plates of middle-distance spikes enhance flexibility to reduce fatigue, focusing only on the forefoot, but this spike has a full-length plate. Additionally, to accommodate distances like the 1500m, there is cushioning sponge at the heel.
Forefoot type with a front-centered shape
The sole has a significant curvature. The curvature of the sole is well-matched with the pin arrangement, making it particularly recommended for those with a forefoot running style or those of the A1 type in the 4 stance theory (who find it easy to exert force when the center of gravity is on the inside front). The jagged part of the sole seen in side photos serves as a non-slip feature, providing grip beyond the number of pins. However, since it is designed with a strong emphasis on rebound, the grip feeling of grabbing the ground is not very pronounced. As can be seen from the side, white sponge material is also installed in the forefoot area as the midsole. This makes the feel underfoot soft, and there is no worry about developing blisters despite the hardness of the sole.
