Learn Something New -- Day 3

I walk. I walk a lot. Every Day. I frequently have to buy new walking shoes. Recently, I decided to calculate just how often I buy new walking shoes. My shoes should last me for about 500 miles (that's what an article on the internet said.) I figure I walk about 40 miles per week times that by 12.5 and it comes out to 500 miles. Well, perhaps my walking shoes should last that long but most times, depending on the weather, I have to buy them more often. Rain, snow, and icy roads take a real toll on walking shoes. So I figured I buy new walking shoes about every 6 months. I sure hope Easy Spirit Shoes don't go out of business!
