Purchased about a year ago, but I switched to jumping events and haven't used them much, so they've been stored at home. ○ MIZUNO ○ Sprinting spikes (100m, 200m, 400m, hurdles) ○ X BLAST NEO2 / X BLAST NEO2 / U1GA230611 / ○ For all-weather tracks ○ 27.5cm I don't think there are any noticeable scratches or stains, so I believe they can still be used for competition, but I will sell them to someone who understands that they are used and have been stored at home.
