Foot problems in men and women
The hypothesis that women will have more foot-related problems compared to men has been proven to be true.
Choosing the right type of footwear and one that fits perfectly is important in caring for our feet. Footwear should be comfortable and not feel tight when worn. Normally, a half to one inch space is needed between our longest toes and the inner edge of the shoe. As we grow older, the size of our feet will change, and we should change our shoes accordingly.
Try to repeat the experiment by using participants of different age groups.
The experiment can also be modified to compare the effects of wearing high heels or sandals on women’s feet.
