This is an excellent product, once you learn how to twist out no matter how you stop they keep your shoes on the crank through all types of conditions. It can be if-ie to lock in, so it is important to keep your shoes just before the heal to keep from slipping if you miss a lock taking off. Usually this is not a problem, but if you've stopped up hill it takes some practice to get it right, and a bump or wiggle can keep that from happening. This effect is worse when the cleats are new, they must get broken in before locking-in gets easy. I have thought about burnishing the cleat effect to ease this process, but I always ride first giving the extra effort to twisting and pushpulling to get a lock. They will last about a year or two until a hard push unlocks causing the foot to slip. Get a new pair and start again
Good product
Why mess with what works.
These aren't so premium because they take minutes off your TT or anything... they're premium because they allow you make a small lateral movement of your cleat if center-neutral doesn't work for you. I got some for my bulky winter boots that otherwise would lightly rub my cranks. Problem solved. Additionally, they span the breadth of the slots in an SPD shoe so that your platform is wider than with the ultra-narrow 'race' cleats that come stock with the new Eggbeaters, which place all your weight on just the center bridge of the outsole that exists between the slots. I've heard reports that these engage the new eggbeater pedal slightly less easily than the race cleat, but haven't experienced any problem myself.
