Fox River Mills has manufactured premium wool and performance socks in Osage, Iowa since 1900, producing the Norsk ragg wool hiking socks, Wick Dry performance liners, and Classic Wool crew socks that outdoor enthusiasts across America have trusted for over 120 years.
Heritage & History
Fox River Mills was founded in 1900 in Osage, Iowa, a small town in the rolling farmland of Mitchell County where wool processing and textile manufacturing had been local industries since the late 19th century. The company began as a traditional hosiery mill, knitting wool socks for farmers, loggers, and working men in the cold Iowa winters. The quality of Iowa-made wool socks spread regionally, and Fox River expanded its distribution as its reputation for durability grew.
The Norsk Heavyweight Ragg Wool Crew sock — Fox River's signature product — became the standard recommendation for serious hikers and outdoor workers who needed warmth, cushioning, and moisture management in extreme conditions. The classic two-ply Norwegian ragg wool construction, with its rough-cut unprocessed wool that creates natural air pockets for insulation, became synonymous with 'hiking sock' for generations of American outdoors enthusiasts. Over 120 years after the company's founding, Fox River still knits in Osage.
Made in Osage, Iowa
Fox River Mills' Osage, Iowa factory has been producing socks since the company's founding at the turn of the 20th century. The facility produces a full range of wool and performance socks: the Norsk Heavyweight Ragg Wool hiking sock, the Wick Dry Ultra-Lightweight liner for wearing inside boots, the Hanging Rock merino hiking crew, and the Classic Wool everyday crew sock.
The Norsk's traditional ragg wool construction — featuring unprocessed, naturally lanolin-rich wool fibers — provides exceptional insulation even when wet, a property that has made wool the material of choice for outdoor workers and hikers in cold, wet conditions for centuries. The Wick Dry Auras liner provides a next-to-skin layer that moves moisture away from the foot before it can cause blisters — designed to be worn inside the Norsk or other wool socks for maximum moisture management on long hikes. All Fox River products carry the Made in USA designation from an Iowa factory that has outlasted a century of American manufacturing change.
