Yup.
Here's an interesting video on barefoot running by two guys I follow and respect.

Next level is trying to run on grass.

Ouch!! You probably need to build up to the gravel road barefoot my friend!

Haha :)
Yes... that's next level.
I'll stay on sand for a while....

However, sand isn't harmless as well... Little grains grinding between the toes combined with salty water... I have one cut and it burns :)
