If you've upgraded your pedals to the Dura Ace 9000 series, no doubt you're putting in the miles. When your cleats wear out, as they will, you'll need the Dura Ace 9000 Cleats to keep you locked in. These are the 9000 series Blue cleats, which give you one degree of float, a new option for Shimano that previously only offered six degree or zero degree float. This gives you the efficiency and power transfer of a fixed cleat with just a little room for comfort. It's something the pros have enjoyed for a few seasons now. The one degree of float originates from the center of the cleat, which also works better with your foot's natural movements while riding.
