Strap on the snowshoes and see you at
the top. A bitter cold, pre-dawn start.
Thanks to SmartWool a sunrise workout
never felt so good.
It’s all about the fit. That’s why we get
a little geeky over our PhD socks. We
measure foot temps. Pressure points.
We “field test” endlessly. Some call it
a workout. We call it R&D. All to create
socks that go overboard on comfort
How? First, SmartWool does the heavy
lifting of managing moisture and keeping
feet warm. Then our 4-Degree Fit
System hard-wires comfort into every
step. Better cushioning. Dry, warm feet.
WOW TechnologyTM makes our PhD
socks more comfortable. More durable.
Maybe we’re geeks. But we love it.
You will too.
