I'm liking the Shimano SPD pedals more and more esp. the dual sided models. They are so convenient on my commutes where it involves lots of clipping in and out. I have 3 pairs of shoes with these cleats and they all work well exactly the same. All 3 are the single point release but I've had no problem releasingwhen I had to but also no accidental releases. One time, in a slow turn, my front wheel slipped out on a wet stone surface and my foot popped out no problem saving myself from an embarrassing situation. These were a bargain on sale at BTD.
I've used this style cleat for approximately 25 years and like it. With the purchae of new shoes I thought also time to buy new cleats.
The release is a bit tighter than I am used to with my old well worn cleats...guess that's to be expected. Hope for a short break in period to ease the effort necessary for release.
