I’m a big fan of barefooting whenever possible. However, in the city, I almost always wear either my Vibram’s, my Vivo Barefoots, or my Brooks Cross Country Flats.
A recent news piece by the San Diego News Network explains why – some asshole(s) buried razor blades in the ground in a children’s park. Not only that, but it’s happened before.
I’m always very cautious in the parks around SF, and try to be very cautious when I’m in the streets as well. As the old saying goes – an ounce of prevention is worth a pound of cure.
That goes for things like – using good form when lifting weights; making overt agreements with play partners when you’re playing games; going slowly at first, then speeding things up; warming up; and now – playing in the park!
Scout your area first, look around for broken glass or other hazards. Wear shoes. If you’ve looked around, and feel safe, you can go barefoot, but I guess you do so at your own risk.
Oh yeah, and if you see or hear of some idiot planting razor blades in a public space – call the police and report them.
