Upper with overwhelming fit due to lateral stability features
The upper part is designed with lateral stability features in the midfoot to accommodate high-speed races. It also incorporates lightweight and less stretchable materials with excellent moisture-wicking properties. As a heat countermeasure, larger ventilation holes than usual are placed in the reinforced areas of the upper, allowing for airflow inside the shoe. This makes it a recommended shoe for those who tend to get blisters on their feet due to moisture. However, the fabric in the forefoot may feel heavy when wet. Compared to other MIZUNO products (such as Geospush 7 and Geospart LD), the texture of the tongue feels pleasant, and the materials used provide good comfort.
A wider upper that can accommodate athletes with broader foot widths
The width is designed to be wider compared to spikes from other manufacturers, making it easy for athletes with wide feet to wear. The width rating is 3.5 out of 5, making it the third widest long-distance spike overall, following MIZUNO's Geospart LD (4 out of 5) and ASICS LD Japan. The spikes that are tied for third place include ASICS's Gunlap SC and Gunlap 2. The toe area has a thin fabric at the tip, raising concerns about durability with prolonged wear. On the other hand, the heel is secured with a hard material, providing a sense of stability.
A sole with a stable feel similar to marathon shoes
It features six fixed pins, 2.5mm in length. The pins are evenly distributed in the forefoot, and the flat sole allows for stable ground contact. It has a standard shape for long-distance spikes. Additionally, the sole has a grip similar to that of marathon shoes, allowing for a firm hold on the ground. The hardness of the sole is designed to be on the firmer side among long-distance spikes, resulting in high responsiveness. The wearing sensation is that the sole is thin and hard, providing a feeling of rebound. Moreover, due to the thin sole, you can feel the pins directly on the sole of your foot, giving a sensation close to being barefoot. Because of the flat sole, it is difficult to achieve the propulsion feeling typical of the currently popular thick-soled shoes, but it is recommended for those confident in their leg strength.
A flat sole with no incline and stable feel
The sole has almost no curvature. Due to its flat shape, it differs from long-distance spikes from NIKE or New Balance that may have quirks when wearing, making it suitable for a wide range of users from beginners to advanced athletes. The flat sole and flexible hardness allow for various landing methods, including forefoot landing, full-foot landing, and heel-to-toe transitions.
