Customer Reviews

HUNTINGLIFE REVIEW Review by Kevin Paulson
The Magnum SF-3 Socks really wowed me. I needed new socks. My sock drawer had been getting pretty lean from either missing pairs, a son who likes his dad's socks when he cannot find a pair of his own, and just general use; so I jumped at the chance to fill my sock drawer up with some quality socks that were just a little bit different then the white socks that have been a staple in my household for years. I opted for the SF-3 in Desert Tan and boy am I glad I did. These socks are pretty much heaven. The toes and heel have a slight bit of padding. The socks breathe well, but what I like the most is the compression strap through the middle of the foot. This compression strap is light, breathes easy, and keeps the sock tight to my foot. I will absolutely be wearing these in all but the most extreme conditions for quite some time. (Posted on 1/16/13)
Perfect! Review by Eric
I always get blisters, cracks in my skin and have an overall bad experience when I am in the elements. These socks really stood out from the rest. First off, they are comfortable right from day one. The color is nice and they are soft. I used them in the hot jungle of Central America which was muddy, wet, and stinky. Each day my feet remained dry, there were no cracks, no smell, and I was happy to be able to walk miles on end with no discomfort.

I should also note that I was wearing the Magnum Precision WPi boots as well. My feet thank you! (Posted on 1/15/13)
THEY'RE WORTH IT!! Review by Max Dilley
I am always looking for socks. My lifestyle is such that it is demanding on my circulatory system. I usually need to switch socks quite a few times during the day. These amazing socks, for whatever reason, I am able to keep on all day and night and some if need be. They are so worth the money!! (Posted on 11/3/12)
