We've owned our boat for 20 years. I never go out into the cockpit with shoes on. Benny's right. Ain't worth the potential damage. I can drop my anchor and raise it with my eyes closed, but I wouldn't go close to thinking about doing anything on our boat with those toe-stomper things on. Simply too dangerous.
Reminds me of a decade ago: I broke my leg skiing. 84.6% of the folks I met who "used to ski" told me that they stopped because they broke a bone. On their "last run," whether that was at 4:00 pm or the r=first run of the day, it was their very LAST run.
Same thing with flip - flops. Why bother? Don't say you haven't been warned.
Be "foot safe."
