Is the T4021 worth $27.95?

At $27.95 at Sock Annex as of November 4, 2026, it is near the bottom of its recent range. The lifetime guarantee and reinforced heel and toe make the cost per year low for heavy boot wearers.

How does it compare to Darn Tough's lighter tactical socks?

The T4021 is midweight with full terry cushioning, so it is warmer and more padded than the brand's lightweight tactical models. Choose it for cold weather or long days on your feet, and a lighter sock for hot climates.

Will it fit in my boots?

It is a boot-height sock, about 11 inches heel to cuff, so it works with most 6- to 8-inch boots. The midweight cushioning takes up some room, so very snug boots may feel tight.

What is the warranty?

Darn Tough backs its socks with an unconditional lifetime guarantee. If they wear out, you can send them in for a replacement.

Best pricing tends to come from multi-pair bundles and seasonal sales. As of November 4, 2026, the lowest new price was $27.95 at Sock Annex.
