US mill-knit performance socks with cushion zones
What changes: Merino-led with unconditional lifetime guarantee, higher price
Brand profile
American maker of activity-specific padded performance socks, knitted in North Carolina since 1953 and known for zone-cushioned hiking, running and work styles.

The line splits by use — hiking, running, tennis, walking, work, military, diabetic care — plus a thinner Experia range, rather than one all-purpose sock.
Density-mapped cushioning sits at the heel, ball and toe to reduce blisters and impact, which is the whole point of the construction.
Family knitting began in Statesville, North Carolina in 1953, and Jim Throneburg's 1980 cushioned sock created the category; assets changed hands in July 2025.

Thorlo makes activity-specific padded socks in Statesville, North Carolina, where Lewis and Mattie Thornburg began knitting in 1953. Jim Throneburg's 1980 cushioned athletic sock defined the category, and the line still splits by use: hiking, running, tennis, walking, work, military and diabetic-care styles, plus the thinner Experia sub-brand. Construction centers on density-mapped padding at the heel, ball and toe to cut blisters and impact. Assets of the manufacturer, renamed TH Hosiery Mills, were bought in July 2025 by New American Hosiery Company, a Wilson Brown Sock Company and Circufiber joint venture.
