FAQ

Q: How warm are these compared to the Pro Gear Boot Socks?
A: The Trekker socks are heavier, thicker, and more insulating — built for extreme cold or stationary outdoor work.

Q: Can they be worn as house socks?
A: While soft enough for indoor comfort, they’re designed for boot wear. Concrete and rough surfaces will shorten their lifespan.

Q: Are they breathable despite being heavyweight?
A: Yes. The bison/merino blend wicks moisture efficiently and regulates temperature even when heavily insulated.
