Description: A freehand drawing illustration showing a pair of women's casual shoes. The primary difference between men and women's running shoes is the width of the shoe. Compared to the corresponding men's shoe, women's shoes are built wider in the forefoot and toe area and narrower in the heel, reflecting the gender differences in foot shape. Furthermore, men's shoes are generally wider and sized larger than women's shoes. Some shoes, despite being branded as the same shoe for different genders, have different midsole materials or heel support, affecting the fit, comfort and even weight of the shoe.
