The designation “CN 38” refers to a shoe size originating from the Chinese sizing system. It is a numerical representation used to indicate the length and width of a shoe suitable for a foot of a corresponding size. As an example, footwear marked with this designation is intended to comfortably accommodate a foot measuring a specific length, typically expressed in millimeters.
Understanding size designations like this is crucial for ensuring a proper fit, which contributes to foot comfort, prevents potential foot problems, and optimizes athletic performance when applicable. Historically, different regions and manufacturers have employed varied sizing systems, leading to potential confusion when selecting footwear. The existence and standardization of systems like the Chinese one attempt to mitigate such ambiguity within their respective markets and contexts.
