Actually, at such a low speed I find it only helps focus. It's meditative, similar to how a labyrinth is an ancient meditative walking device.

Also, our bodies evolved walking 10+ miles per day. Not standing in one place for hours. The broader point is about reconciling modern lifestyles with the evolutionary past that we are still largely bound by.

How low a speed are we talking here for maximum focus? Have you tested with different speeds? Would be interesting!
