The Basics of Shoe Sizing
Before diving into style-specific variations, it's essential to understand the basics of shoe sizing. In the US, women's shoe sizes are measured in increments of a third of an inch. A US size 4 corresponds to a foot length of approximately 8.19 inches (20.8 cm). However, shoe fit is influenced by more than just length; factors such as width, arch height, and toe shape also play crucial roles.
