How much bigger is a men's shoe than a women's shoe?

On average, men's shoe sizes are roughly 1.5 to 2 sizes larger than women's shoes. For example, a women's size 8 typically corresponds to a men's size 6.5 or 7. This difference in sizing is due to variations in foot shape and width between genders. However, it's important to note that sizing can vary by brand and style.
