What to know about Smartwool
Socks are the core business
The line splits into Hike, Run, Ski and Everyday socks, with merino base layers and knit-to-shape Intraknit pieces built out around them.
Ski-instructor origin, corporate scale now
Started in 1994 by two Steamboat Springs ski instructors; VF Corporation has owned it since 2011 and runs it from Denver alongside Icebreaker.
Merino at accessible prices
Wool socks and base layers sit in a lower-mid price tier, positioned for daily wear as much as for trail, run and ski use.
How Smartwool fits
Overall fit
true to size
Smartwool apparel is generally reported as true to size with a trim, athletic cut typical of merino base layers, though some find the slimmer pieces snug across the chest and shoulders.
Tip: Order your usual size; size up only if you want to layer over base layers or prefer a looser feel.

Brand facts
Smartwool makes merino wool socks, base layers, and everyday apparel, founded in 1994 by Steamboat Springs ski instructors Peter and Patty Duke after cold, wet days on the slopes.

VF Corporation has owned the brand since its 2011 Timberland acquisition and runs it from Denver next to sister label Icebreaker. Recent work includes the Second Cut sock-recycling program and a 2025 resort partnership with Alterra Mountain Company.
