How do these compare with the old PhD Outdoor socks?

Same fit and technologies, updated with recycled nylon, more durable construction, revised mesh zones and a refined fit. Owners of the PhD line generally find the update comparable or slightly better.

Are they warm enough for cold-weather hiking?

They are light cushioning, so they suit three-season hiking. For winter or cold feet, Smartwool's midweight or heavy cushioning hike socks are the better match.

Will they last through heavy backpacking?

Indestructawool zones reinforce high-wear areas, but light cushioning and merino blend wear faster under heavy loads. Many owners get a full season or more of regular day hiking.

Do they fit true to size?

They follow Smartwool's men's sizing and the 4 Degree system gives a close, performance fit. If you are between sizes or prefer a roomier sock, size up.

Can I wear them in summer?

Yes. The mesh zones breathe well, though the crew height adds warmth. Many hikers wear them comfortably in warm weather.

One pair of crew socks. No liners or other accessories are included.
