High heels are often the culprits – they push the body weight forward onto the front metatarsals, and often squash the toes together into a point, causing calluses and corns. When the body weight is pushed forward, it changes the way someone walks, which could have long-term detrimental effects.
Bunions can also be the result of ill-fitting shoes.
Men, on the whole, wear shoes that are more comfortable than women's high fashion shoes are, leading to a lower rate of foot problems.
