These boots were made for walkin'... Whether your child is wearing boots, sneakers or pretty little Mary Janes, walking to school is a must on Oct. 7, as it's the 10th annual International Walk to School Day.

Walk to School Day has its roots in the U.K., where walk to school week was introduced in Hertfordshire in 1994. By 2000, the concept had made its way around the world and the first International Walk to School Day included participants in Canada, Great Britain, the U.S., Ireland, Cyprus, Gibraltar, and the Isle of Man. (Australia and New Zealand ran walks throughout their school year.)

From a handful of participating nations, participation swelled to 21 countries in 2001, and by 2007, millions of students and parents in 47 countries made the trek to school.
