I can confirm this. With ATACs I also had to trim off additional rubber around the cleat recess in the sole before the shoe would would engage properly with the pedal.
They would still clip in before I trimmed them (probably securely enough for normal use with brakes) but it was definitely with more of a dull "thud" than a crisp "snap". You could even see if you clipped in the shoe in and flipped the pedal over to take a look – the rubber of sole was getting in the way and stopping the pedal from fully clipping in. I ride brakeless and I experienced too many scary unclips and almost binned the shoes for fear of death. However, since I trimmed the sole back they are perfect – pedals lock in with a loud, crisp snap and feel much more secure. No more unclips in the past 5 months.
It sucks having to take a Stanley knife to a pair of almost £100 shoes though!
