AvatarByAndrea Broussard Fitting & Sizing

When it comes to buying shoes, understanding size conversions across different measurement systems can be a real challenge. Whether you’re shopping online or browsing international brands, encountering unfamiliar sizing labels is common. One such label that often raises questions is the “CN 38” shoe size. What exactly does this size mean, and how does it compare to other sizing standards you might be more familiar with?

Navigating shoe sizes can feel like decoding a secret language, especially since various countries use different units and numbering systems. The CN sizing system, primarily used in China, follows its own unique scale, which can make it tricky for shoppers to find the perfect fit without some guidance. Knowing what a CN 38 shoe size represents is essential for making informed purchasing decisions, ensuring comfort, and avoiding the hassle of returns.

In this article, we will explore the meaning behind the CN 38 shoe size, how it fits into the broader world of shoe sizing, and what you need to consider when encountering this label. Whether you’re a seasoned shopper or new to international footwear, gaining clarity on CN sizes will help you step confidently into your next pair of shoes.

Converting CN 38 to Other International Shoe Sizes

Understanding how a CN 38 shoe size translates into other sizing systems is essential for accurate fitting, especially when purchasing shoes internationally. The CN size system, commonly used in China, corresponds closely with the length of the foot in centimeters. A CN 38 typically means the shoe is designed for a foot approximately 24 cm long.

When converting CN 38 to other shoe size standards, the following approximate equivalents are generally accepted:

  • European (EU) size: 38
  • US Women’s size: 7.5 to 8
  • US Men’s size: 6 to 6.5
  • UK size: 5 to 5.5
  • Japanese (JP) size: 24

It is important to note that these conversions can vary slightly depending on the manufacturer and shoe style. Therefore, consulting brand-specific size charts when available is recommended.

Size System Equivalent to CN 38 Foot Length (approx.)
China (CN) 38 24 cm
Europe (EU) 38 24 cm
United States (Women’s) 7.5 – 8 24 cm
United States (Men’s) 6 – 6.5 24 cm
United Kingdom (UK) 5 – 5.5 24 cm
Japan (JP) 24 24 cm

Factors Affecting Shoe Size Accuracy

While numerical conversions provide a general guideline, several factors can influence the actual fit of a shoe marked as CN 38:

  • Foot Width: Standard shoe sizes often assume a medium width. Individuals with wider or narrower feet may find that a CN 38 does not fit as expected.
  • Shoe Style and Design: Different designs (e.g., running shoes, dress shoes, boots) may fit differently even when labeled the same size.
  • Manufacturing Variances: Slight differences in production processes or materials can affect the shoe’s internal dimensions.
  • Brand Differences: Some brands may adjust sizing standards to suit their target market, leading to variations in what CN 38 represents.
  • Measurement Method: CN sizing is based on foot length, but if foot measurement was taken incorrectly, the selected size may not match the actual foot length.

To improve fit accuracy when purchasing shoes marked CN 38:

  • Measure your foot length accurately, preferably at the end of the day when feet are slightly swollen.
  • Consider trying on shoes in-store if possible, or ordering from retailers with good return policies.
  • Review brand-specific size charts and customer reviews for insights on fit.
  • Take into account foot width and arch height, which can affect comfort beyond length measurements.

Practical Tips for Selecting the Correct CN Shoe Size

Purchasing shoes using the CN size system requires attention to detail to ensure comfort and proper fit. Here are some practical recommendations:

  • Measure Foot Length Precisely: Use a ruler or measuring tape to measure from the heel to the tip of the longest toe.
  • Compare Measurements to Size Charts: Use reputable size charts that convert foot length to CN sizes.
  • Allow for Slight Adjustment: Consider adding 0.5 cm to 1 cm to the measured foot length to accommodate foot movement and sock thickness.
  • Check for Width Options: Some manufacturers provide width fittings (e.g., narrow, regular, wide); select accordingly.
  • Account for Sock Thickness and Usage: If shoes are intended for sports or thick socks, choose a slightly larger size.
  • Read User Feedback: Customer reviews often provide valuable information about true-to-size fitting or if the brand runs large or small.

By following these guidelines, consumers can better navigate the CN sizing system and select shoes that offer optimal comfort and performance.

Understanding CN 38 Shoe Size in International Standards

The designation “CN 38” refers to a shoe size based on the Chinese (CN) sizing system. This system is commonly used in Mainland China and is distinct from other international sizing standards such as US, UK, and European (EU) sizes. Understanding what a CN 38 shoe size equates to in other systems is essential for accurate shoe fitting, especially when purchasing footwear from Chinese manufacturers or retailers.

The CN shoe sizing system is primarily based on the length of the foot in centimeters, rounded to the nearest whole or half size. A CN 38 generally corresponds to a foot length of approximately 24.0 to 24.5 centimeters.

CN Size Foot Length (cm) Approximate EU Size Approximate US Men’s Size Approximate US Women’s Size Approximate UK Size
38 24.0 – 24.5 38 – 39 6.5 – 7 7.5 – 8 5.5 – 6

When converting CN sizes to EU, US, or UK sizes, slight variations may occur due to differences in measurement methods and manufacturer tolerances. Therefore, it is advisable to consult brand-specific size charts where possible.

Key Factors in Converting CN 38 to Other Shoe Sizes

Several factors influence the accuracy of converting CN 38 shoe size to international standards:

  • Measurement Methodology: The CN system is based on foot length in centimeters, which is a direct measurement, whereas some systems rely on shoe length or other parameters.
  • Gender Differences: US and UK sizes vary for men and women, so conversions depend on the intended gender-specific size.
  • Manufacturing Variability: Shoe sizes can vary slightly between brands or styles, even within the same nominal size.
  • Width Considerations: CN sizes generally do not specify width, unlike some US and UK shoe sizes, which may impact fit.

How to Measure Foot Length for Accurate CN Sizing

To determine the correct CN shoe size, measuring the foot length accurately is essential. Follow these steps to ensure proper sizing:

  1. Place a piece of paper on a flat surface against a wall.
  2. Stand with the heel against the wall and foot flat on the paper.
  3. Mark the longest toe position on the paper.
  4. Measure the distance from the wall (heel) to the mark (toe) in centimeters.
  5. Round the measurement to the nearest half centimeter to find the corresponding CN size.

For instance, if the foot measures 24.3 cm, a CN size 38 is appropriate, as it covers 24.0 to 24.5 cm foot length.

Practical Tips When Buying Shoes in CN 38 Size

  • Consult Brand-Specific Charts: Different manufacturers may have slight deviations; always check the specific brand’s size chart.
  • Consider Trying Shoes On: If possible, try on shoes to ensure proper fit, especially if the brand or style is unfamiliar.
  • Account for Socks and Inserts: Consider the thickness of socks or any insoles when selecting size.
  • Review Return Policies: When buying online from Chinese retailers, ensure there is a clear return or exchange policy in case the size does not fit.
  • Pay Attention to Width: If foot width is an issue, look for brands that offer width options or order one size up for comfort.
