Socks are typically marked with either a shoe size or an indication of small, medium, large, extra large, etc.  For example, "S, M, L, XL, etc." would be the alpha size.  When shopping, you may have to contact the manufacturer if you want the most accurate conversion from the alpha size to shoe size or visa versa.

First lets try to get a handle of shoe measurements because they are relevant.

At best, its own published standards for shoe sizes conversions only serve as "a good compromise solution" for shoe-buyers

A shoe size is an indication of the fitting size of a shoe for a person. There are a number of different shoe-size systems used worldwide. While all shoe sizes use a number to indicate the length of the shoe, they differ in exactly what they measure, what unit of measurement they use, and where the size 0 is positioned. Some systems also indicate the shoe width, sometimes also as a number, but in many cases by one or more letters. Some regions use different shoe-size systems for different types of shoes.  Yes, this becomes very confusing.

Shoe sizes often measure the length of the foot not the actually shoe.  However, really depends on the manufacturer and how they create their points of measure (learn about size specs & points of measure).

Many sock retailers, brands & manufacturers list the approximate fit of the socks based on shoe sizes (not sock sizes).
