An Indoor Skater's Dream Come True

Firm is for older floors, but is still great roll. About 91A hardness. Extra Firm is getting harder with a little less grip but great roll...Super Firm is as hard as we get (around 94A) and rolls like crazy but still has good grip for floors with a fairly fresh coat of plastic that are larger.
