This set is for American-style football cleats (gridiron football, not soccer). They will not fit soccer cleats. Is it time to refresh your cleats? This complete cleat & wrench set will have you up and running in no time. These studs are constructed of high-quality composites and molded onto zinc-plated steel posts for strength and durability. Plus, wedge shaped teeth at the contact point will keep them firmly locked in place, all game long. The 1/2-inch length is the most common all-purpose size and they are a direct fit for all major brands.
