In recent years there has been an explosion in barefoot running, as well as the purchase and use of ‘minimalist’ running shoes that more closely resemble barefoot running by encouraging the balls of the feet, between the arch and toes, to hit the pavement first. A new study found that a significant number of experienced runners, age 30 and older (40 percent of men and 20 percent of women), maintained a heel-first running pattern — which naturally occurs when wearing a shoe with an elevated heel — when running without shoes.
