By the way, there was the Ethiopian world champion runner, who run barefooted. It was his trademark.

However do not try this at home, as good running shoes protect your knees. I would also recommend the special belt, where you can keep your water bottle for hydration.

Running is very good exercise. Firstly, it is the diversity. And besides, it is good for urban security. Because the ability to run fast and long may safe one in some dangerous situations.

The speed is one of the main characteristics of a fighter jet, the same applies for an "urban warrior".
