Product Size Chart: Men's Socks

Men's socks are usually sized according to shoe size / foot length, rather than exact foot width. Common sock labels include EU shoe-size ranges such as 35–38, 39–42, 43–46, as well as S, M, L, XL or One Size.

How to Measure

Foot Length: Stand on a flat surface and measure from the back of your heel to the tip of your longest toe.

For everyday socks, your usual shoe size is generally the easiest and most reliable reference.

Choosing the Right Size

If your shoe size falls between two sock ranges, choose the larger size for comfort, especially for thicker or less-stretchy socks.

Dress Socks — usually thinner and more flexible.
Casual / Crew Socks — generally have moderate stretch.
Sports Socks — may fit more snugly for support.
Thermal Socks — thicker construction can feel tighter inside footwear.
Compression Socks — should follow the manufacturer's specific sizing chart, as calf and ankle measurements may also be required.

Please Note

Sock sizing is not completely standardized between brands. Fabric stretch, thickness, elasticity, and sock style can affect fit.

Use your shoe size or foot length as the primary reference. Brand-specific or product-specific sizing information should take priority when available.
