Shoe Shopping Tips
Best Time to Shop
Shop for shoes in the afternoon when your feet are at their largest. Feet naturally swell throughout the day.
Try Both Feet
Most people have one foot slightly larger than the other. Always fit for the larger foot.
Width Matters
Don't just focus on length. The right width prevents pinching, blisters, and long-term foot problems.
Consider Sock Thickness
Bring the type of socks you'll wear with the shoes, or account for thicker socks in winter boots.
The Shoe Size Converter with Fit Notes turns your foot length, brand, and width into sizes across US, EU, UK, Japan, and Australia. It adds brand tweaks and narrow or wide advice so you get fewer exchanges and happier feet.
Heads up
Conversions are guidance. Fit can vary by model. Do a quick at home try on and check return policies before you wear them out.
How the Shoe Size Converter Works, foot length to size
- Measure foot length. Trace both feet in the afternoon. Measure heel to longest toe to the nearest 0.1 in or 0.5 cm. Use the larger foot. I stand against a wall, heel touching, so the ruler stays honest.
- Pick units. Inches or centimeters.
- Choose a brand or stay generic.
- Select width. Narrow, medium, wide, extra wide.
- Tap Convert.
Converting other items too, try the International Size Converter for quick cross brand checks.

Brand shoe size tips, Nike vs Adidas sizing
These are starting lines, not verdicts. Your feet get the final say. Running shoes for sunny miles, protect your skin with the SPF Calculator.
- Nike. A touch narrow. If you are wide, consider half size up.
- Adidas. Often true to size. Ultraboost can feel snug, half up if between.
- New Balance. Many widths. 2E and 4E available in core lines.
- Hoka. True to size in length, roomy toe box, wide options in key models.
- Vans. Low volume, slightly narrow. True to size for most, watch width.
- Converse. Chucks run long and narrow. Many size down half for a secure fit.
- Dr. Martens. Length close to true. Break in takes a few wears. Medium width.
- Clarks. Classic last, often true to size, good width selection.
- Birkenstock. Firm footbed. Regular width fits wide feet, Narrow fits many mediums.
- Louboutin. Very narrow. Often size up, limited widths.
- Generic path. Match by length and width, then try within half a size if the last looks narrow.
Measurement guide, foot length to size
- Trace both feet on paper, afternoon is best.
- Measure heel to longest toe with a ruler.
- Use the larger foot to choose size.
- Wear the socks you plan to use.
- If you use orthotics or your feet swell later in the day, try half size up and recheck width.

Width decoder, narrow vs wide shoes
- B width, common women’s medium.
- D width, common men’s medium, women’s wide.
- 2E width, men’s wide.
- 4E width, men’s extra wide.
Crosswalk, women’s medium is B, men’s medium is D. Women’s wide is often D, men’s wide is often 2E.
Feel on foot, more width lets your forefoot splay without that pinched, end of day ache.
Shopping tips for a sure fit
- Try both feet, they are siblings, not twins.
- Socks matter, match thickness to your use.
- Walk a quick lap on a hard floor, not carpet, you feel slippage faster.
- Break in takes a few wears, leather relaxes, knit stretches.
- Read return windows before you click buy.

First hand example, Converse fit
I plug in 9.75 in, medium width, Converse.
The converter returns, US 7.5, EU 40.5, UK 6.5, JP 25.5, AU 7.5.
Fit note, Converse runs long. If you like a snug Chuck Taylor fit, try US 7.
Width fork, if your forefoot is wide, keep US 7.5 for Chucks, or try a wider friendly model like Jack Purcell.
FAQs, international sizing and widths
Why do sizes differ by region?
Each region uses a different scale, the tool maps them to your foot length.
How accurate are brand adjustments?
They reflect common lasts and real feedback. Models vary, use return friendly stores.
If I am between two sizes, which do I pick?
For sport or no break in, go bigger. For canvas or leather that stretches, start closer to snug.
How do kids and men’s conversions differ from women’s?
Same length logic, different scales. As a rough guide, women’s US 8 is about men’s US 6.5, then run the converter to confirm.
When should I size up for insoles?
If you add a thick insole or orthotic, go up a half size and recheck width.
Do widths match across brands?
Not perfectly. Use the width decoder, then read the brand note for that last.
