Thank you for viewing. I purchased these on Mercari, but they don't fit my feet, so I am listing them for sale. ・No box (I will carefully package them for shipping) ・Running distance: Approximately 8km, including the previous owner (used once for a 1,500m race, twice for 3,000m races, and for warm-ups and strides) These are mid- to long-distance spikes designed for ease of movement and lightness [Recommended events: 1,500m~10,000m]. These long-distance spikes have been improved to be lighter and allow for smoother movement when running 1,500m~10,000m. The nylon plate maintains rigidity in the midfoot while allowing for flexibility in the forefoot, generating propulsion during the push-off phase. FLYTEFOAM is used in the midsole to achieve lightness. Despite its thinness, it provides cushioning and offers a soft ride. The urethane outsole improves grip. The upper uses HL-0 mesh, which has a comfortable feel and spring-like elasticity. It provides excellent fit and prevents foot movement that can lead to power loss during running. This pair pursues ease of movement, "wrapping around the foot," with functions for long-distance running sought in every detail. These can be used without any problems by those wearing spikes for the first time or those who do not have the strength to handle thick-soled spikes. If you have any questions, please feel free to comment. Thank you for your consideration.
