Reviews

My New Colorado Mountain hiking “go to” socks!

"Fit is perfect, doesn’t move/slide in my boots. Seems to be no issue with rubbing or blisters on potential hot spots (toes, heels), but haven’t taken them on long hike yet. I usually like higher merino content in the blend so maybe I’ll check out out some of your heavier weight socks? Thanks for making such great quality here in USA!"

— Charles I. (5/5)

Serious powerwalkers need these socks

"I often power-walk three with my dog on paved roads. The T4021 Boot Midweight Tactical have generous cushioning in all the right places. I own six of these, and I intend to buy more; they're tough socks that mitigate the pounding I get on the road."

— Steve K. (5/5)

A Quality Gift!

"Purchased these for my neurodivergent husband who can be particular about the way his socks feel and wears socks out quickly. Initial impressions were positive, and after a few washings he is still impressed with the compression level and quality of the sock. These were originally purchased as "wear around the house" socks, but they've quickly become part of his regular rotation because his feet are so comfortable."

— Meghan A. (5/5)

Great socks!

"Most comfortable socks I’ve worn. I bought them for use on large wildfires and have switched to wearing them daily. The only suggestions that I have are: 1- describe the socks for laymen, not people who understand your product. 2- keep the t4022 in stock more."

— Joshua M. (5/5)

My favorite dress socks

"First, I have Darn Tough socks that saw weekly wear for 13 years and none of them have worn out. As to these socks, they are lighter than the ones I have but better cushioned which is nice for 71-year-old feet that still have to be clad in dress shoes several times every month. I now own several pairs."

— Stuart W. (5/5)

First time user

"Thickness, padding, and feel are good. So far I like them. It would be a help if you included washing and long term care instructions with them. Or at least on your web site."

— Mike W. (4/5)

These are the Boot Socks to get

"As you may see on my Micro Crew w/Lightweight review, this is the brand, spend money on them, as much as you can tolerate. I only have a few of the "boot" socks like this so far, but they are far superior to the "dress boots" socks I had previously. Speaking of which, do yourself a favor if you wear boots, and get some 3D printed insoles made for your exact feet. The result is more like "steel-toed upgraded feet" than anything as sloppy as a "shoe. ""

— Wilson B. (5/5)

These are in the pack

"These are in the pack heading to West Point Class of 2030 with my Lake George N. Y. grandson. They are on several recommendation lists."

— Karen L. (5/5)

Nice!

"Very thick and soft. I love how my feet feel in these socks!🧦"

— Karen L. (5/5)

They're great! Had a really

"They're great! Had a really old pair from 2008 or so that are still around, decided to get a bunch of new ones and toss out the old inferior socks sitting around. Quality,and the comfortable cushioning the socks are pretty good. They do fit a little more snug but not losing circulation so thats a pass."

— Jason C. (5/5)
