I have the red Look Keo cleats with the gripping tabs on the bottom. Clipping into these cleats is a major problem (clipping out is very easy). I never had this problem with the Delta's. I'm wondering if it's the grips. I was at the LBS today and noticed the Keo's they had in stock did not have the grips. Has anyone else had this problem? Maybe I could just pull the tabs off and use cleat covers for walking.
