Sock Sizes
Accessories · 6 specs
Direct Answer
Sock sizes represent the physical length of the sock foot in inches (e.g., standard Size 9-11 or Size 10-13), mapped directly to US Men's, US Women's, and European shoe sizes to prevent heel slippage and toe constriction.

Why Sock Size Numbers Differ from Shoe Sizes
A common point of confusion is buying Size 10-13 socks thinking they only fit Size 10 to 13 shoes. In the hosiery industry:
- The label '10-13' refers to actual foot length in inches (10 to 13 inches), which corresponds to US Men's Shoe Sizes 8 to 12.5.
- Buying socks that are too small causes heel pouch pull-down inside shoes and friction blisters; buying oversized socks causes bunching at the toe box.
