I see a big world wide movement towards less shoes, makes sense doesn't it. How many thousands of years did we develop with no shoes? Mind you they didn't have concrete then did they - I wouldn't fancy running barefoot on concrete too much.
Horse people have been working towards this for years.
Interesting thing is we are finding out that horses don't need shoes even the ones who work on concrete and asphalt every day.
So hey why not people too?
