How to Measure Your Feet
Step-by-Step Guide
- Stand on a piece of paper with your heel against a wall
- Mark the longest point of your foot on the paper
- Measure the distance from the wall to the mark in inches
- Round up to the nearest inch for your US sock size
- Repeat for both feet and use the larger measurement
Measurement Tips
- Measure feet at the end of the day when they're largest
- Wear the type of socks you plan to use with the shoes
- Consider the thickness of different sock types
- For children, measure every 3-4 months as feet grow quickly
- If between sizes, choose the larger size for comfort
Different Sock Types
Athletic Socks
Usually have cushioning and moisture-wicking properties. May run slightly smaller due to compression features.
Dress Socks
Thinner material, typically true to size. Made from finer materials like merino wool or cotton blends.
Compression Socks
Designed to be tight-fitting. Often sized differently than regular socks - check manufacturer sizing charts.
Frequently Asked Questions
How do I know what size socks to buy?
The easiest way is to use your shoe size. US sock sizes correspond directly to foot length in inches, while general sizes (Small, Medium, Large) are based on shoe size ranges.
Are men's and women's sock sizes different?
In the US, sock sizes are based on foot length, so they're technically unisex. However, men's and women's shoe sizes differ, which affects the sock size conversion.
What if I'm between sock sizes?
Choose the larger size for comfort. Socks that are too small can cause discomfort and wear out faster, while slightly larger socks are usually fine.
How often should I measure my child's feet?
Children's feet grow quickly, so measure every 3-4 months. You may need to buy new socks more frequently than shoes as tight socks can be uncomfortable.
