Reliable MIZUNO quality upper
The upper features a lace + belt design that follows the previous model, made of synthetic fiber (mesh part) and artificial leather (enamel part). Feature ① The thinness of the tongue (the part covering the instep in the center of the upper) and shoelaces Feature ② Reinforcement tape attached to the mesh fabric at the top of the toe The tongue and laces are overwhelmingly thinner compared to other companies' long jump spikes, similar in thinness to Mizuno's representative model, Chrono Inks. This thinness allows the foot and laces to be tied as closely as possible, creating a sense of unity between the foot and shoe. As a result, shoe slippage is eliminated, providing a high level of fit. Additionally, this sense of unity makes the spikes feel lighter than their actual weight. The reinforcement tape reduces lateral sway during takeoff and minimizes power loss.
Wide design that fits Japanese feet
Since this spike seems to have been made by a Japanese manufacturer for Japanese people, the width of the spike is relatively wider. While it is not wider compared to the Adizero LJ, it has a more spacious toe width compared to the Long Jump Pro (Long Jump PRO)/ASICS and Zoom LJ4 (Zoom LJ4)/NIKE. The heel gives a solid impression. Perhaps due to the use of mesh fabric on the toe side, the heel part made solely of artificial leather feels sturdy. Additionally, not only in contrast to the mesh fabric, but this heel is made the hardest among the entire upper of the spike. This heel part is sewn with multiple layers of artificial leather.
Sole that creates a reassuring sense of stability
This model has become 10g lighter due to the removal of the rebound agent in the forefoot midsole (the yellow part of the previous model's sole) as a result of the revision of Article 140 of the World Athletics regulations, making it comparable in weight to ASICS's Long Jump Pro. The removal of the rebound agent has made the sole itself thinner, allowing for slightly easier flexing of the toe. It features a sharkskin structure in the forefoot and heel areas. The internal pillars connecting the front and back of the sole function like a single plate sole. Regarding the sharkskin, it has been changed to a slightly more protruding version that was released by a certain S company in a previous custom order, improving friction. Also, like the previous model, there are claws at the toe that are not found in other companies, allowing for power transmission right up to the takeoff point. There are nine pins, the same as the Long Jump Pro (1-3-5), but the pin configuration is 2-3-4, providing greater stability for the Field Geo LJ-C.
Flat sole that is easy to take off
The curvature of the sole has been made flatter than the previous model. It can be said to be considerably flatter compared to the previous Field Geo LJ-B (Field Geo LJ-B), Long Jump Pro (Long Jump PRO)/ASICS, Adizero LJ (Adizero LJ)/ADIDAS, and Zoom LJ4 (Zoom LJ4)/NIKE. However, this flat sole does not give the impression of being difficult to run on, and there is not much resistance to increasing speed during the approach. The ease of running, which was inferior to the Long Jump Pro (Long Jump PRO)/ASICS in the previous model, has also improved, resulting in a well-balanced spike suitable for advanced users.
