Perfect Fit Tips

📏

Measure Both Feet

Feet can be different sizes. Use the measurement of your larger foot.

🕐

Measure in the Afternoon

Feet swell during the day, so afternoon measurements are more accurate.

👟

Consider Shoe Type

Athletic shoes often run larger, while dress shoes may run smaller.

🧦

Account for Socks

Measure with the type of socks you'll wear with the shoes.

📐

Check Width Too

Foot width is as important as length for proper fit.

Understanding Shoe Sizing Systems

Major Sizing Systems

US Sizing: Based on the length of the last (foot form) in inches, with different scales for men's and women's shoes
UK Sizing: Similar to US but typically runs about 0.5 to 1 size smaller
European (EU) Sizing: Based on the length of the foot in centimeters, multiplied by 1.5
Japanese (JP) Sizing: Uses actual foot length in centimeters
Mondopoint: International standard based on foot length and width in millimeters

Important Notes

Shoe sizes can vary between brands and styles. Always try on shoes when possible, and consider:

Different brands may fit differently even in the same size
Athletic shoes often run larger than dress shoes
Feet can swell during the day, so measure in the afternoon
Consider the width of your foot, not just the length

Example: Converting US Size 9 (Men's)

Given: US Men's size 9

Conversions:

UK Size: 8.5 (US men's size minus 0.5)
EU Size: 42.5 (calculated from foot length)
Foot Length: ~27.0 cm
Japanese Size: 27.0 (same as foot length in cm)

Note: These conversions are approximate and can vary between manufacturers.

Frequently Asked Questions

Why do shoe sizes vary between brands?

Different manufacturers use different lasts (foot forms) and have varying interpretations of sizing standards. This can result in the same numerical size fitting differently across brands.

Should I size up or down when converting?

Use the exact conversion as a starting point. If you're between sizes, consider the shoe type: athletic shoes often run large, while dress shoes may run small. When in doubt, choose the larger size.

How accurate are these conversions?

These conversions are based on standard sizing charts and are generally accurate within 0.5 sizes. However, individual foot shape, brand variations, and shoe style can affect the actual fit.
