Upper designed for easy run-up like a short distance
The upper is similar to the company's long jump spikes, Long Jump PRO, featuring a typical lace and belt configuration. It uses synthetic leather as the material, which becomes more comfortable with use. As it breaks in, it can fit the foot with laces, creating a sense of unity between the foot and the spike. However, as it breaks in, the hold may decrease, making it easier to feel instability during steps. Please be cautious about the timing for replacement. Regarding breathability, it is covered entirely with synthetic leather, so expectations are low. The fully covered design is necessary to prevent sand intrusion and to maintain the shape of the foot upon impact, making it an unavoidable aspect.
Foot width designed to be just right for Japanese people
Regarding shoe width, it has the best fit among the same triple jump spikes, Field Geo AJ/MIZUNO, Adizero TJ/ADIDAS, and TRIPLE JUMP ELITE/NIKE. Additionally, as mentioned earlier, the upper is entirely synthetic leather, making it less likely to stretch. (If it does stretch, it means the hold on the foot during takeoff is lost, so replacement is recommended.) With a narrow shoe width and a non-stretching upper, those with wider feet like typical Japanese people may feel cramped. Therefore, the number of people who can wear them is limited. Please consider your own foot width as well.
Sole designed for easy run-up like a short distance
Regarding the sole, the forefoot is similar to the company's long jump spike, Long Jump PRO. One point of difference is that the part that is sharkskin in the long jump spike has been replaced with a rubber-like anti-slip material. The nine pins are relatively numerous, matching the number found in the Field Geo AJ/MIZUNO. Of these nine pins, four are located at the base of the toes (such as the ball of the foot), which catch during landing, while the five pins on the forefoot contribute to the push-off. Additionally, compared to the 1-3-5 configuration of the Triple Jump PRO, the Field Geo AJ/MIZUNO has a 2-3-4 configuration, allowing for better pin release during takeoff, enabling a jump without losing speed.
Pin configuration that balances takeoff and run-up
Similar to the company's Long Jump PRO, the curvature of the sole is designed so that the five pins, arranged in an arc to be directly under the base of the toes, form a curve with the apex at these pins. When standing upright, these five pins make contact with the ground, and as the run-up begins, the four pins at the toe side (the front half of the foot) engage and function. This structure helps stabilize the five pins during stationary and takeoff phases, while minimizing interference during the run-up, reducing the likelihood of deceleration due to friction. This further enhances the ease of the run-up, following the upper.
