Shoe Size Standards

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

The new shoe size standards will be enforced for all shoe products starting July, 2020. Shoe sizes which do not meet the standards outlined below might be removed from display on detail pages after July, 2020. This applies to newly created ASINs as well as existing ASINs. Therefore, we highly encourage all sellers to begin adopting the new standards starting May, 2020 and proactively updating shoe sizes that do not satisfy future requirements. 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 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 for.
    • Options: Male, Female, Unisex
  • Age Range Description [Required]: Select the age range for which the product is intended for.
    • Options: Adult, Kid, Baby
  • Footwear Size System [Required]: The footwear size system is used to display a specific shoe sizes to customers on-site relevant in the marketplace.
    • Examples: In the UAE, only EU shoe sizes will be displayed on the website.
  • Footwear Size Age Group [Required]: Select the age group for which the shoe size is intended for.
    • Options: Adult, Big Kid, Little Kid, Toddler, Infant
  • Footwear Size Class [Required]: Select the class of shoe size representation.
    • Examples:
      • Numeric - will display values such as 37 EU, 37.5 EU, 38 EU
      • Numeric Range – will display values such as 37/38 EU, 38.5/39 EU
      • Alpha - will display values such as One-Size, Small, Medium, Large, X-Large
      • Alpha Range – will display values such as Small/Medium, Medium/Large
      • Age - will display values such as 6 Months, 2.5 Years (up to 5 Years)
      • Age Range – will display values such as 6-12 Months, 3-4 Years (up to 5 Years)
  • Footwear Size Width [Required]: Select the applicable shoe width.
    • Examples: Medium, Wide, X-Narrow
  • Footwear Size [Required]: Select the applicable shoe size.
    • Examples: 38, 38.5, 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 37, 37.5, 38 will be displayed in Footwear Size.
  • Footwear To Size Range (If range) [Required, dependent on selected footwear size class]: Select the ending shoe range value. This will be combined with the previous Footwear Size selection to build a range. For example, if you want to list a product as 38/39 EU, you would select Footwear Size value as 38 and Footwear Size To Range value as 39. Amazon will combine these values as 38/39 EU.
    • Examples: 38/39, 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 Size To must be greater than the value selected in Footwear Size. For example, we will allow 38/39 (where 38 was selected as the Shoe Size and 39 was selected as the Shoe Size To Range). We will reject values such as 39/38 (where 39 was selected as the Shoe Size and 38 was selected as the Shoe Size To Range).

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.

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 = EU 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

The separate fields that exist for each of the individual footwear size elements 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.

Valid Shoe-Size Inputs

The link below provides a list 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 labeled 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. You can also 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.

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
