The toe seam in a sock and why you feel it

Short answer: The seam across the toes is the only place in a sock with a ridge. If it is thick, you feel it in the shoe all day.

Why there is a seam

A sock is knitted as a tube and closed at one end. Closing it needs either stitching or linking. Stitching makes a small ridge. Linking makes almost none.

How to feel the difference

Turn the sock inside out and run a finger across the toe end. A stitched seam feels like a clear ridge. A linked closure feels almost flat. See bamboo socks for men.

When it matters most

In running shoes and walking boots where the toes are pushed forward. There a thick toe seam can leave a red mark or a blister. See bamboo socks for women and bamboo compression socks.
