Shoe Size Standards

Standardisation of shoe sizes is part of a larger initiative to improve the overall shopping experience through ingestion of consistent and accurate data. Starting June, 2020, Amazon is introducing a new set of attributes specific to shoe sizes that will be used to display standardised and consistent size values to on-site customers.

The new shoe size standards will be enforced for all new shoe products listings starting October, 2020. We highly encourage all selling partners to begin adopting the new standards starting June, 2020 on both new and existing ASINs. Additionally, we recommend spending time reviewing the standards outlined below and the Frequently Asked Questions.

To ensure that your shoe sizes display properly on the website, we request you to submit shoe sizes in US size system and to include the following information for each shoe size you submit:

Shoe Size Requirements

  • Target Gender [Required]: Select the gender for which the product is intended.
    • Examples: Male, Female, Unisex
  • Age Range Description [Required]: Select the age range for which the product is intended.
    • Examples: Adult, Big Kid, Little Kid, Toddler, Infant
  • Footwear Size System [Required]: The footwear size system is used to display marketplace-specific shoe sizes to customers on-site.
    • Examples: In AU, only US shoe sizes will be displayed on the website.
  • Footwear Age Group [Required]: Select the age group for which the shoe size is intended.
    • Examples: Adult, Big Kid, Little Kid, Toddler, Infant
  • Footwear Gender [Conditionally Mandatory]: Select the gender for which the shoe size is intended for.
    • Examples: Women, Men
    • Notes:
      • The value selected might or might not be equal to Target_Gender selection.
      • This selection becomes required when Footwear Age Group is equal to Adult.
  • Footwear Size Class [Required]: Select the class of shoe size representation.
    • Examples: Numeric - will display values such as 7, 7.5, 8
      • Numeric Range – will display values such as 7-8, 8.5-9
      • Alpha - will display values such as One-Size, Small, X-Large
      • Alpha Range – will display values such as Small-Medium, Medium-Large
      • Age - will display values such as 6 Months, 2 Years
      • Age Range – will display values such as 6-12 Months, 2-3 Years
  • Footwear Width [Required]: Select the applicable shoe width.
    • Examples: Medium, Wide, X-Narrow
  • Footwear Size [Required]: Select the applicable shoe size.
    • Examples: 8, 8.5, Small, 6 Months
    • Notes:
      • The values displayed are dependent on the value selected in Footwear Size Class. For example, if Numeric was selected in Footwear Size Class, then only numeric values such as 7, 7.5, 8 will be displayed in Footwear Size.
  • Footwear To Size [Conditionally Mandatory]: Select the ending shoe range value. This will be concatenated with the previous Footwear Size selection to build a range. For example, if you want to list a product as 8-9, you would select Footwear Size value as 8 and Footwear To Size value as 9. Amazon will concatenate these values as 8-9.
    • Examples: 8-9, Small-Medium, 3-6 Months
    • Notes:
      • This selection becomes required when Footwear Size Class is equal to Numeric Range, Alpha Range, or Age Range.
      • Populate this field only if you are listing a product with a shoe size range.
      • The value selected in Footwear To Size must be greater than the value selected in Footwear Size. For example, we will allow 10-11 (where 10 was selected as the Footwear Size and 11 was selected as the Footwear To Size). We will reject values such as 6-5 (where 6 was selected as the Footwear Size and 5 was selected as the Footwear To Size).

  • For Adult Unisex products [Conditionally Mandatory]: Provide the opposite gender values for all of the information listed above.
    • Examples: 8 US Women/6 US Men, Large Women/Medium Men
    • Notes:
      • This selection becomes required when Target Gender is equal to Unisex and Footwear Age Group is equal to Adult.
      • This selection is intended to capture the gender specific equivalent shoe size information. Therefore, if Women is selected in the first set of shoe size information, Men should be selected in the second set of shoe size information (and vice versa).

Each element of information provided above must match to a valid value (see Valid Shoe-Size Inputs section below) and must adhere to the field level conditional requirements. Below is a comprehensive list of requirements:

Attribute Description Attribute Requirement Definition
Target Gender
  • target_gender is required on all submissions
Age Range Description
  • age_range_description is required on all submissions
Footwear Size System
  • When marketplace_id = 111172 footwear_size.size_system = us_footwear_size_system
Footwear Age Group
  • footwear_size.age_group is required on all submissions
  • footwear_age_group must equal the value selected in age_range_description
Footwear Gender
  • footwear_size.gender is required on all Adult submissions
Footwear Size Class
  • When footwear_size.age_group = adult only show footwear_size.size_class values numeric, numeric range, alpha, alpha range
  • When footwear_size.size_class = alpha or alpha range, only show alpha size values
  • When footwear_size.size_class = numeric or numeric range, only show numeric size values
  • When footwear_size.age_group = infant, toddler, little_kid, big_kid show footwear_size.size_class values numeric, numeric range, alpha, alpha range, age, and age range
Footwear Width
  • footwear_size.width is required on all submissions
Footwear Size
  • When footwear_size.age_group = infant and footwear_size.size_class = age or age range, only show months values
  • When footwear_size.age_group = toddler and footwear_size.size_class = age or age range, show all age values (months and years)
  • When footwear_size.age_group = little_kid, big_kid and footwear_size.size_class = age or age range, only show years values
Footwear To Size
  • When footwear_size.size_class = numeric range, alpha range, or age range, the footwear_size.to_size attribute becomes required
  • When a shoe is sized as a range there are specific values which are not valid in the footwear_size.to_size field based on the value provided in the footwear_size.size field. For example, if footwear_size.size is equal to 8, then footwear_size.to_size must be greater than 8.
For Adult Unisex products
  • When target_gender.value = unisex and footwear_size.age_group = adult then one footwear_size.size is required for both footwear_size.gender values
  • The actual footwear size for a given pair of shoes must either be all ranges or all exact sizes
  • When target_gender.value = unisex and footwear_size.age_group = adult the size class must be the same for both variants

Errors

When you upload a shoe product, if the required sizing information is missing or the sizing information is incorrect or inadequate, one or more of the following might result:

  • The size is rejected and the feed, template submission, or 1 by 1 submission fails. A related error message appears in your processing report.
  • The ASIN is no longer buyable.

To correct the error, resubmit the feed with the required information included as described above. Below is a list of applicable error messages specific to footwear_size :

Applies when:

Footwear Size System = US Footwear Size System

Footwear Age Group = Adult

Target Gender = Unisex

You may not provide conflicting/ inconsistent 'class' values in attribute 'footwear_size' for 'unisex' products.

Applies when:

Footwear Size System = US Footwear Size System

Footwear Size is greater than or equal to Footwear To Size

The value of 'size' must be less than the value of 'to_size' in attribute 'footwear_size'.

Website Display

Using the separate fields that exist for each of the individual footwear size elements, they will be automatically combined into a customer friendly format once the required sizing information has been provided. This value will be published to the size_name attribute for XML, or the size field for text file feeds and displayed on-site. See Valid Shoe-Size Inputs section for examples of received values and the corresponding published size_name values.

Shoe Width

Shoe Widths can vary depending on the brand, retailer, or country, and the same width designation can mean something different for Men’s Shoes than it does for Women’s Shoes. For example, a "B" width for Women is Medium, but a "B" width for Men is Narrow while a "3A" width for Women is Extra Narrow [XN], but an Extra Extra Narrow [XXN] width for Men.

Amazon no longer uses alphanumeric width designations and instead leverages its own universal width scale, ranging from 3X-Narrow to 3X-Wide, with intelligible values that can be easily understood by the end customer.

Accepted Shoe Width Values:

  • 3X-Narrow
  • XX-Narrow
  • X-Narrow
  • Narrow
  • Medium
  • Wide
  • X-Wide
  • XX-Wide
  • 3X-Wide

Valid Shoe-Size Inputs

The links below provide lists of valid values for size_name in addition to the footwear size elements and additional attributes used to construct the valid size. Use the column labelled Valid Values to view all size values that are considered valid. You can select a value in the Valid Values column to see which footwear size elements and Target Gender and Age Range Description were used to generate that valid value. Or, you can start from the Target Gender column, and moving from left to right, populate applicable values in each column to see the valid value that will be generated based on the elements you have selected.

Note: Target Gender and Age Range Description are existing attributes that drive conditional requirements and must be populated.
  • The Footwear Size attributes are listed twice to capture Unisex Adult sizes.
  • Values in Red which state "OR" are not the official values, can be either/or. This is applicable to Target Gender and Footwear Gender.

Unisex Sizing

If your shoe is a valid unisex-adult shoe style (For example: Converse All Star), you may ascribe it a unisex size value (for example: 9 Women/7 Men) to allow customers to find it in both the Women’s and Men's departments. You should not attempt to ascribe unisex sizes to non-unisex brands/styles with the intent of increasing product discovery. Doing so erodes the customer experience and damages customer trust. All unisex size entries will be audited and invalidated if they are misrepresented as unisex.

Note: Unisex sizes values will always lead with the Women’s size ahead of the Men’s size and will be provided in the required unisex sizing format highlighted in the Valid Shoe-Size Inputs section above.
