No shoes to buy. No stress over stability or cushion. No loosing toe nails. I like it.

Run like a kid again!
At my gym the treadmills are much busier than the pool.
What I really like about it is, anybody can run, and while I'm probably a slow swimmer, not everybody can swim. When I hit the end of the lap and spin around for another lap there is voice in my head that says, "you are amazing."
