Please stop wearing sandals when you work out.
I really don't even know how that's possible.
I don't like having to see your feet and imagining them sweating all over the machinery. I have a problem with feet (except for Caderyn's cute baby feet).
Chacos are okay to hike in and hang out around the water in, but seriously, I don't think you need to wear them at the gym.
I thought there was a rule against that...oh wait no...that was in Missoula where they had that. Too many hippies :)
