Is the T4033 worth $33.95?

At $33.95 at Amazon as of November 4, 2026, it is a fair price for a heavyweight merino sock with a lifetime guarantee. The cost per year of use is low if you wear it hard in cold weather.

How does it compare with Darn Tough's midweight hiking socks?

The T4033 is noticeably thicker and warmer, with cushioning across the whole foot. Midweight hiking socks fit closer and suit three-season use better.

Will it fit inside tight boots?

It is a bulky sock, so it works best in boots with room to spare. Size down or choose a lighter sock if your boots fit snugly.

Is it machine washable?

Yes. Wash in warm water and tumble dry low; the merino blend holds up to regular laundering.

What sizes and colors does it come in?

Darn Tough lists it in multiple men's sizes and a few colorways. Check the specific store listing for what is in stock.

Darn Tough socks rarely discount deeply. Watch for seasonal sales at outdoor retailers and compare the 5 stores listing it new.
