Walking is a great way to take exercise. It's something that we all know how to do - so it doesn't require any special training.
It doesn't require any special equipment either - apart from a good comfortable pair of shoes that is, and you need those anyway.
The Skechers Go Walk range is specifically designed to be lightweight and comfortable. They have a cushioned insole for shock absorption and a flexible, traction improving outer sole.
Have a look at some of the styles in the Go Walk 2014 range below. There are plenty to choose from.
