Not enough underfoot padding
Size: Medium, Color: Coyote Brown 4 Pairs
Socks are well made but would be better if they had thicker padding under the toe and heal.

Very good quality for the price

My expectations of the quality was low. Surprisingly tho the socks were pretty good and the quality surprised me. They are soft and comfortable. Definitely recommend.

Nice Quality Socks
Color: Coyote Brown, 3 Pack, Size: Large, Color: Coyote Brown, 3 Pack, Size: Large
Hate shopping for clothes online, even for socks. Looked at lots of different brands and settled on these due to their customer reviews which seemed positive. I ordered 2 of the 3 packs of the coyote brown in the large size. The color is pretty accurate to the advertisement. You can see my picture of the new sock unrolled straight out of the box alongside a tape measure that shows the length. The socks seem like they are very good quality. The aren't thin or see through like some of the cheaper options I considered. To me the are similar in thickness to a name brand white tube sock like Hanes or Fruit of the Loom. The large size is 18 1/2 inches long in it's natural shape and easily stretches over the calf but below the knee. I wanted to lighten the color to more closely match my work pants and tried washing them 5 times with bleach mixed in the washer. They held their color, and elasticity even with the bleach, so I didn't get the color change I was hoping for but goes to show that under normal washing (without bleach) the color won't likely fade anytime soon. The have great stretch and elasticity and stay up above the calf all day without sliding down. Definitely ordering these again when needed.
