Soft upper made of a single piece of fabric without seams
The upper is secured with laces. Using a very thin and lightweight material, you can feel a weightlessness as if you forget you are wearing them. Additionally, the seamless structure of the upper is one of its features. With almost no seams, it wraps around your foot like a single upper, providing a very high fit. Because the upper is very thin and soft, it allows for easy dorsiflexion of the toes, and during takeoff, you can control your toes freely without feeling pressure from the upper. However, please be cautious about durability as the fabric is thin in exchange for lightness.
Upper that wraps around the entire foot
The toe area is slightly narrower. Therefore, if you have slightly wider feet, you may feel a bit cramped when using them. The structure has few seams and looks like the entire upper is made from a single part, giving it a unique hugging sensation and feeling of pressure. Therefore, it is recommended for athletes who prefer a snug fit. The heel area is simply reinforced with artificial leather. Since there are no special belts for tightening, if the heel shape does not fit, you may experience chafing or gaps.
Spikes that do not interfere with practical athletes
The pins are arranged as 1-2 (fixed pins) - 1-3 (only center fixed pins) from the toe, with seven pins concentrated in the center, making it easy to shift your center of gravity. On the other hand, the concentration of the arrangement in the center means that external grounding can easily sway left and right. Therefore, these spikes are suitable for intermediate to advanced users who require grounding technique. To enhance grip on the ground, the sole has unevenness that helps firmly grasp the ground. The rebound is designed to be moderate, requiring sufficient muscle strength to master. Additionally, the plate is made thin in pursuit of lightness, so caution is needed as it may cause foot pain when used for practice.
A curvature and rebound characteristic of short distances
The curvature of the sole is very steep, and it adopts a very light and responsive plate, allowing you to gain a powerful rebound by utilizing the curvature of the sole. It is extremely light and has strong rebound, and while it does not interfere with running, it requires sufficient grounding technique and muscle strength, making it difficult to master. However, if you can master it, you can achieve strong rebound with short ground contact time, allowing for a more bouncing run. Additionally, due to the curvature, it is easier to shift your center of gravity forward, making it a recommended spike for athletes who want to grasp the sensation of center of gravity movement during grounding.
