At the end of the dat tundragumski is blowing the Look 'problem' out of all proportion! The reality is that Look KEO platform is no worse than other SPD SL style cleat systems (especially if you use 3rd party KEO cleats) in the grand scheme of things. Look cleats wear a bit faster as Look use a much softer plastic than other manufactures, one problem is that they wear quicker & the plastic they use isn't that grippy (hence their grip cleats), however with original KEOs I've not had reason to take a knife to cleat & shave off splintered plastic from a bad miss-clip, which can't be said for SPD SL, I-CLIC, Mavic Road Cleats & the 3rd party KEO cleats.
So if you don't want those problems you've got to look at radically different cleat designs, that means MTB/CX clipless systems or one of the Speedplay road series (I'd recommend the
Zero if you go down that road), of course these have different sets of compromises leading to other problems.
