These cleats are a good deal if they're on sale (daily special). However, note that these do not have the rubber grips at the bottom and may be more slippery if you're walking around. I prefer the grey cleats with the 6 degrees of float which give me a nice balance of security and keep my knees happy.
I've standardized on Mavic or Look pedals on all my bikes, and these are my go-to cleats for road pedals. Stock up when they're a Daily Special so you have them on hand when you realize $%, these are worn out and you really need them. Tips - (1) Take a Sharpie and outline the position on the bottom of your shoes before you swap them so you get them back in the same spot, and (2) put a dab of grease on the bolts so they won't seize due to moisture later.
I've been riding Look since the beginning of clipless tech. Solid feel, easy to clip in, and good durability. A good cleaning and a light coat of lubricant will keep the squeaks away.
Look Keo cleats have been around for so many years there's not much I can say about them, either you like the pedals and cleats or you don't. However, there's nothing like a new set of cleats to give you a solid connection between your foot and the pedal. I generally let my cleats get too worn before replacing them. I shouldn't and I won't in the future.
Just replaced my cleats after having used the original cleats for over 2 years with close to 8,000 miles of riding and I'm a little embarrassed to admit a moderate amount of walking also. These original cleats were still very easy to click-in & out but I thought it would be prudent to replace them.
I've always been using the (slightly more expensive, it turns out) 'grip' version of these cleats. I didn't pay attention when ordering, but I now know the difference! Does the job on the bike, but I much prefer the grip version even for short hallway walks on tiles... Will make sure I get the right version next time )
Have used Look Keos for several years now. I like the greater float they afford over Shimano. If you do use these cleats, however, I suggest getting a set of the rubber cleat covers. They will last twice as long. You buy the models with the impregnated wear pads for double the price, but I believe these are a far greater value IF you don't mind carrying your cleat covers with you.
