Style / Height
Swiftwick products are available in several styles, each defined by type and fiber blend in a family, or "line" and within that line, they carry a common identity. The ZERO is the starting point in each line, moving up an inch to the ONE, the TWO and so on -- up to the knee for the TWELVE. The name of your sock is a FOUR, which is the style, and you may own a FOUR in several different lines. Size charts with each product highlight standard small, medium and large or extra large construction. We keep it simple.
