I can't run them as I have very knackered knees.
So I use Time ATAC pedals instead as I think they are easier to get in and out of but give you a lot more movement around the pedal body. They are however heavy buggers unless you spend money to get the carbon ones. But in saying that they are only heavy compared to other clipless systems. And lighter than flats apart from silly money ones. The real advantage of the though is that they just don't get clogged with mud
like SPD pedals can.
I use them on MTB and road bikes as well. A useful thing is that for some reason you can normally pick them up cheap on Ebay
. I've got 2 pairs on the go and my total outlay is less than £30.
And I only fall over because of them going uphill on super slow techie stuff for some reason.
Something to look out for though, and I seem to suffer badly from this. is that I habitually unclip with my left foot first so when I'm stopped I will only have that foot free to balance on. So when I do have to unclip in a hurry my right foot can be a bit tight in comparison.
Oh, and Mavic shoes, very comfy and you can walk pretty normally in them.
