There are numbers of differences between the male and female foot. For example, the male’s foot has much more square shape that that of a female. The female foot is broader across the toes than a male’s. Also, a female’s foot has a narrower heel than a male’s. Females are usually at higher risk for feet problems than males. This is because females wear high heels often. This puts all the wait on the toes and therefore puts strain on the foot and leg muscles.
