You know that frustration when you order shoes online and they feel totally wrong? Yeah, me too. Last month I bought running shoes that gave me blisters because I guessed my size wrong. That's why getting your hands on a proper shoe size chart for womens and mens footwear is crucial. This guide will show you exactly how to nail your size every time – no more wasted money or uncomfortable shoes.
Why Shoe Sizes Vary So Wildly
It's crazy how a size 9 in one brand feels like a 10 in another. I learned this the hard way when my favorite sneaker brand updated their design and suddenly my usual size was too tight. Shoe sizing differs because:
- Regional systems: US, UK, EU, and Japanese sizes all use different numbering
- Brand variations: Nike tends to run narrow while New Balance is roomier
- Shoe type: Dress shoes fit tighter than athletic shoes by design
- No universal standard: Each manufacturer sets their own specs
How to Measure Your Feet Correctly
Forget what size you think you wear – let's measure properly. Grab paper, a pen, and a ruler.
Simple Measurement Steps:
- Place paper on hard floor against a wall
- Stand straight with heel touching the wall (wear socks if you usually do)
- Mark longest toe point on paper
- Measure between wall and mark in centimeters or inches
- Do this in the evening – feet expand during the day!
I made the mistake of measuring barefoot when buying hiking boots. Bad idea – my thick socks made them painfully tight. Always measure with the socks you'll actually wear.
Foot Width Matters Too
Most people forget width. Use a tailor's tape around the widest part of your foot while standing. Here's what those letters mean:
- Narrow: Women's AA-A, Men's B-C
- Medium: Women's B, Men's D
- Wide: Women's C-D, Men's E-EE
- Extra Wide: Women's E+, Men's EEE+

Brand-Specific Sizing Quirks
Here's where that shoe size chart for womens and mens needs real-world adjustment. Based on customer reviews and returns data:
| Brand | Fit Tendency | Recommendation |
|---|---|---|
| Nike | Runs narrow, small | Size up 0.5 from your usual size |
| Adidas | True to size | Stick with your measured size |
| New Balance | Runs wide | Narrow feet size down 0.5 |
| Dr. Martens | Large initially, molds to foot | Size down 1 full size |
| Converse | Runs large | Size down 0.5 to 1 size |
I disagree with some blogs that say Birkenstocks run true to size. In my experience, you need to go down a size – their sizing is bizarre.
Specialty Footwear Sizing Guide
Shoe size charts for womens and mens vary even more with special footwear types. Here's what you need to know:
Athletic Shoes
- Leave 1/2 inch (1.3cm) space at toe
- Feet swell during exercise
- Always try with performance socks
Boots and Winter Footwear
- Account for thick socks
- Heavier boots need more breaking-in
- Consider removable insoles
High Heels and Dress Shoes
- Tighter fit prevents slipping
- Leather stretches over time
- Toes shouldn't hang over soles
Heel slippage is normal in new shoes – up to 1/4 inch is acceptable and will decrease as shoes mold to your feet.
International Size Conversion Tips
Ever bought shoes overseas and been totally confused? Here's how to navigate global shoe size charts for womens and mens:
- US to EU: Add 31 to women's US size (US 8 = EU 39)
- EU to UK: Subtract 33 from EU size then divide by 1.5 (EU 42 = UK 8)
- Japan sizing: Measures exact foot length in centimeters
- Australian sizes: Same as UK sizes
My worst sizing disaster? Buying Italian leather shoes using US-EU conversion without checking the brand's chart. They were two sizes too big.
Solutions for Common Foot Problems
Standard shoe size charts womens and mens don't cover these issues – but I will:
Wide Feet Solutions
- Look for EE or WW width markings
- Brands like Brooks, New Balance, and ASICS offer wide options
- Avoid pointed toe boxes
Different Sized Feet
- Nearly 60% of people have mismatched feet
- Fit shoes to larger foot
- Use inserts for smaller foot
Swollen Feet
- Measure at end of day
- Adjustable closures like laces or straps
- Stretchy fabrics or mesh panels
Shoe Size Chart Wisdom – Your Questions Answered
How often should I measure my feet?
Every 1-2 years. Feet change with age, weight fluctuations, and pregnancy. I was shocked when my size increased half a size after hiking the Appalachian Trail.
Why do kids' shoe sizes use different systems?
Children's sizes have unique scaling (based on last length rather than foot length). Always check brand-specific charts – kids' sizing is even less standardized than adults.
Do shoe widths change with sizes?
Yes! A women's size 10 wide is wider than a size 6 wide. Width scales proportionally with length in most sizing systems.
Are men's and women's sizes equivalent?
Generally, women's sizes are 1.5 sizes up from men's (men's 8 ≈ women's 9.5). But width differs significantly – men's standard width is wider than women's wide in some cases.
How reliable are shoe store measurement devices?
Brannock devices are accurate when used properly. But I've seen employees misread them. Always verify measurements yourself.
Children's Sizing Simplified
Kids grow fast – here's a quick reference for growing feet:
| US Kids | EU | UK | Approx. Age | Foot Length |
|---|---|---|---|---|
| 10C | 27 | 9 | 2-3 years | 5.8" / 14.7cm |
| 12C | 29 | 11 | 3-4 years | 6.3" / 16cm |
| 2Y | 32 | 1 | 5-6 years | 7.3" / 18.6cm |
| 4Y | 36 | 3 | 8-9 years | 8.7" / 22.1cm |
Smart Online Shoe Shopping Tactics
After years of online shoe fails, here's my battle-tested approach:
- Check brand-specific charts: Never rely solely on standard conversions
- Read recent reviews: Look for comments about sizing accuracy
- Know return policies: Zappos has free returns, some European sites don't
- Order multiple sizes: Worth the hassle to get perfect fit
- Consider materials: Leather stretches, synthetics don't
That shoe size chart womens and mens knowledge becomes powerful when you combine it with brand research. I saved $80 last month by getting the right size on first try.
Seasonal Sizing Considerations
Your perfect summer sandal size might differ from winter boots:
Summer Footwear
- Feet expand in heat
- Sandals often fit differently than closed shoes
- Barefoot sizing vs sock sizing
Winter Footwear
