Buying shoes can be tricky enough in your home country. When purchasing footwear from overseas, questions of sizing and fit get even more complicated.

If you’re looking at a nice pair of shoes on a Chinese retail site only to find the size listed as 40 or 41, how do you know if they’ll fit?

The short answer is that Chinese sizes 40-41 generally correspond to US women’s sizes 9-10.

However, to find your perfect fit, you’ll need to consider more than just size conversions.

This article will cover everything you need to know, from size equivalents to style and width factors to potential sizing issues. Read on for tips on finding the right international shoe size.

Converting CN 40-41 Shoe Size to US

When converting between Chinese and American shoe sizing:

  • Chinese size 40 is equivalent to US women’s size 9 in most brands
  • Chinese size 41 equals US women’s size 10 in most brands

However, there can be variances between different manufacturers and styles.

While major international brands tend to adhere closely to sizing standards, smaller brands may fit slightly differently.

As a general guideline:

  • CN size 40 falls between US sizes 8.5 and 9.5
  • CN size 41 falls between US sizes 9.5 and 10.5

If you fall between standard US sizes, consider sizing up or down by half a size to find your ideal Chinese shoe size.

H3: Men’s Sizing Comparison (100 words)

For men converting Chinese sizes, the sizing differs:

  • Chinese size 40 men’s corresponds to US men’s size 7
  • Chinese size 41 men’s equals US size 8

As with women’s sizes, the fit can vary slightly across Chinese brands. Use the standard conversions as a starting point but be prepared to size up or down.

Factors to Consider Beyond Size

While size conversion charts can provide ballpark US equivalents, many other factors affect achieving the perfect fit:

1. Shoe Style and Width

Consider if a shoe runs large or small for its listed size based on style and proportions. For example, narrow-width shoes may fit tighter and require sizing up.

2. Brand and Manufacturer

Sizing can vary across brands based on the last used and manufacturing standards. Research online reviews mentioning Chinese brand fit compared to US brands.

3. Sock Thickness

Bulkier socks will tighten shoe fit so wear socks similar to those you’ll use with new shoes to determine ideal size.

4. Foot Shape

Those with wider feet may need to size up or select wider-width shoes for comfort. If you have narrow feet you may size down, especially in wide-running brands.

Child vs. Adult Sizing

Pay special attention to size conversions for children’s shoes from Chinese sites. Kids grow rapidly so accurate fit is essential.

While the above women’s and men’s sizes apply to adult shoes, kids follow different guidelines:

  • Chinese youth size 40 is roughly equivalent to US 2.5 – 3.5, depending on the child’s age
  • Chinese youth size 41 equals approximately US kids size 4-5

Again, children’s feet can vary greatly so be extra vigilant in assessing multiple sizing factors beyond standard size charts. Consider wider-width shoes to allow room for growth.

Finding the Perfect Fit

Follow this process when assessing Chinese shoe sizes:

  1. Measure Both Feet
    Use a Brannock device or online guide for measuring foot length and width in cm. Measure at the end of the day when feet are largest.
  2. Compare CM Size to CN Chart
    Match cm length to the corresponding Chinese size.
  3. Cross-reference CN/US Tables
    Check conversion tables to find equivalent US sizes for Chinese sizes.
  4. Evaluate Brand Fit
    Research if that shoe or brand runs large, small, wide or narrow compared to typical sizing. Consider adjusting up or down accordingly.
  5. Order Multiple Sizes If Possible
    When uncertain, order 2 sizes and select the best fit when items arrive. Return the other pair.
  6. Wear Same Socks
    Try on options using socks you’ll normally wear for accurate testing.

Follow this protocol when first buying any shoe brand or style to dial in your size, then order that same size confidently next time.

Common Conversion Mistakes and How to Avoid Them

Converting shoe sizes across regions like China and the US leaves room for errors. But a few key awareness tips can help you sidestep common mistakes:

Assuming all countries follow European or UK sizing scales instead of using unique size numbers. Chinese sizing differs substantially from EU/UK schemes.

Relying solely on standard size conversion tables rather than also factoring in proportions of a specific shoe or brand fit. Straight-size equivalents leave out other key fit considerations.

Not accounting for narrow or wide foot width that requires sizing adjustment. Order wider widths or size up—don’t assume standard medium width will automatically fit.

Buying kids’ shoes without verifying international children’s sizes correspond to US kids versus adult scales. Kids and grownups follow distinct sizing.

Not measuring both feet when one foot is slightly bigger and requires a larger shoe size. Fitting a smaller foot will lead to painful blisters.

They are simply reordering your usual US size without cross-referencing international size charts each time for that brand. Sizing can vary seasonally as styles change.

Ignoring sock thickness and style affecting shoe fit. Bring socks you plan to wear with shoes when trying them on.

With vigilance around these common missteps, you can successfully navigate converting Chinese clothing sizes including understanding what CN shoe sizes 40 and 41 translate to in US women’s sizing and metrics.

Resources for International Shoe Size Conversion

To simplify getting shoe sizes right when importing from Chinese e-commerce sites, take advantage of these helpful conversion resources:

  • International Shoe Size Conversion Charts: Easy reference guides provide comparable sizes across multiple regions.
  • Brannock Device: Measure your feet’s dimensions in inches or cm for accurate fitting.
  • Online Size Conversion Calculators: Input your specifics for CN/US size equivalents.
  • Brand Size Charts: Check brand websites for guides on their unique cuts and sizing per style.
  • User Reviews: Read comments on runs large/small and narrow/wide issues.

Chinese Size Chart Example

For convenience, here is a CN/US women’s conversion chart. Note that US sizes fall between Chinese sizes in some cases:

CN SizeUS Size
CN 35US 5.5
CN 36US 6-6.5
CN 37US 7
CN 38US 7.5-8
CN 39US 8.5
CN 40US 9
CN 41US 10

Alternative Options for Sizing

If trying to determine precise Chinese shoe size equivalents still leaves you uncertain about the best fit, consider these alternatives:

Size Customization

Some brands offer made-to-measure footwear based on your exact dimensions. This avoids size conversion guesswork but comes at a higher cost.

Free Returns

Select Chinese retailers accepting free returns of unworn merchandise. Order multiple sizes then ship back what doesn’t fit.

Local Tailor

Take your favourite shoes to a skilled tailor asking if they can produce custom versions in the materials you provide.

These options let you skip the size conversion process altogether when importing Chinese shoes in popular styles.

Impact of Improper Shoe Size

Wearing improperly sized shoes goes beyond minor discomfort—it can cause lasting harm.

Using inaccurate Chinese to US-size conversion guidelines when purchasing shoes can mean:

  • Slipping, heel instability and ankle rolls in overly large sizes
  • Joint pain from improper gait and lack of support
  • Hammertoes, bunions and corns from constricted toe boxes
  • Ingrown toenails and blackened nails
  • Blisters, calluses and painful skin abrasions
  • Achilles tendon strain and inflammation
  • Metatarsalgia and ball-of-foot soreness
  • Lower back misalignment and tightness
  • Poor posture from wearing irregular sizes

While wearing a less-than-ideal shoe size for a short time likely causes minimal issues, ongoing use of improper footwear can compound biomechanical problems over the long run. Invest time finding your correct international shoe size for healthy feet.

Kids’ Feet Health

Children’s developing feet magnify potential problems from wearing inaccurate sizes over extended durations:

  • Growth plate injuries that cause bone deformities
  • Foot structure deviations like flat feet and high arches
  • Gait and balance impediments
  • Delayed motor skill development
  • Deficient spine, hip and knee alignment
  • Muscle and tendon abnormalities

Ensuring growing kids wear properly fitted shoes provides posture and gait foundations underlying lifelong movement patterns and athletic performance. Don’t cut corners on Chinese youth size conversions.

Tips for Buying Shoes Online

Purchasing footwear digitally instead of in-store means you can’t try items on during selection.

Following certain best practices helps make online shoe shopping simpler:

1. Know Your Size

Measure both feet using a sizing device so you have current length and width metrics handy for comparison.

2. Learn Your Unique Fit

Track styles, brands, sizes and dimensions that work for your feet’s specific proportions.

3. Read Fit Reviews

Consult user comments on that manufacturer’s sizes running large/small compared to other brands before ordering.

4. Compare Sizing Guides

Use company size charts to cross-reference your measurements against their scales for each shoe line.

5. Buy from Retailers Allowing Returns

Send back unworn shoes promptly if the size you received based on guidance feels uncomfortable.

6. Compare Several Stores

Be aware various retailers may use different size data even for the same maker and style. Double-check numbers.

With best practices factored in, buying shoes online directly from Chinese websites can still result in receiving well-fitted footwear once correct global size conversion rates are clear.


Figuring out the equation for converting Chinese shoe sizes to US equivalents takes some work but doing so enables you to access amazing footwear options at affordable overseas prices.

Remember that while Chinese size 40 equates to roughly US women’s size 9 and Chinese size 41 equals approximately US size 10, variations exist across brands and styles that require checking manufacturer size guides to identify your best match.

Kids, men and those needing wider widths have further considerations for Chinese size conversion to find proper American sizing. Carefully measuring your feet’s dimensions in centimetres and cross-referencing multiple size charts allows dialling in the right global shoe size numbers.

Be sure to test pre-owned footwear using the same socks you plan to wear the shoes with for real-world evaluation. Trying multiple sizes when feasible gives a useful comparison for judging the ideal fit. Review site user feedback mentioning issues with larger or smaller fits helps steer decisions.

Ordering well-made shoes directly from Chinese online merchants rewards your effort taken in learning international size translations with great deals. Just apply the knowledge covered here minimizing sizing surprises or comfort sacrifices.
