They're fine. Industry standard. I've had a pair for well over 5 years. Of course there's this pair of Wellgo dual-sided clipless I've had since 1997 w/o a single problem. I use them on my fg. Not a big fan of single-sided clipless. Reminds me of all the reasons I hated toe-clips...pedals kept flopping around everytime I'd pull away from a stop. Aggravating.

Seriously, if one wants clearance for walking while wearing clipless shoes off the bike then one must purchase touring shoes. Atb or mtb shoes aren't designed for pavement. Touring shoes have a deep enough cutout to allow cleat clearance that minimizes 'clicking'. Make sure they're specified as 'touring' shoes. Lake makes a real nice pair. So does Cannondale. Others probably do as well, but those are the 2 with which I have experience.
