the best all-around socks I have ever had
Robert4 years ago
I have worn these socks for everything from hiking to the STP to everyday use. They are amazingly durable, dry quickly when travelling, work well in hot and cold climates, and have never become uncomfortable. Other comments here list a number of criticisms. I have never encountered any of those shortcomings. I've tried socks made of other materials, including Merino wool, from Smartwool and other makers. Those socks have never been as good. These are just better. I just love these.

Bring back cool max ankle height MEDIUM weight
Disappointed4 years ago
I bought these light weight cool max ankle height socks because it seems REI no longer carries the same socks in medium weight. The light weight has poor cushioning - not nearly as comfortable as the medium ones were! Will you be offering the medium again or will I need to purchase another brand of cool max like Thorlo?

Great but not great

This is the second time I’ve bought these socks. I have raynauds and like to wear these around the house and while sleeping because they’re not tight- there is plenty of room and loose fibers to keep heat in. However, the inconsistency between pairs, and shape, even those purchased at the same time, is atrocious. I wouldn’t dream of wearing these with a shoe (regardless of inconsistencies). If that’s what you’re looking for, or if you care if they feel 2 sizes larger/smaller than your last pair, I’d look somewhere else (and not at the merino style, same issues). The two pair shown together were purchased at the same time. I have a third pair which is the same size, but falls between the two pair shown.

Cold ankles!
3 years ago
Thought I was buying the same sock I bought 4 years ago, but they have redesigned it to make it shorter than before -see photos. Used to be “just right” height for 3-season hiking, but now leaves my lower leg/ankle area too cold. Also, thinner than before. Not as cushy - not as supportive for all day activities. Older sock marked REI; newer one says “REI CO-OP”. Newer style seems to slide down on heel, perhaps because there is not as much yarn in ankle area on top to keep it up!

Coolmax hiking socks
1 year ago
I bought these socks for a hiking trip in the Sierra Nevada mountains and I was very impressed by their performance. They are lightweight, breathable, and comfortable, and they kept my feet dry and cool throughout the day. They also have a nice cushioning on the heels and toes, which prevented blisters and reduced fatigue. The socks are made from recycled materials, which is a bonus for the environment. They are durable and easy to wash, and they retain their shape and elasticity after multiple uses. I would highly recommend these socks to anyone looking for a high-quality pair of non-wool hiking socks. They are worth every penny!

stretch out, don't seem durable
5 years ago
I wear a women's size 9 and ordered the M. I've worn them hiking twice. I like the height and the idea of recycling materials to make them, but I don't feel like it resulted in a good quality product, unfortunately. They stretch out (and don't unstretch when washed) and aren't very cushiony. I don't think they will last very long. And I like a little more cushion on my achilles for hiking.

Not true to advertised size
3 years ago
Size was not as advertised. I wear a size 12 and bought the XL. The sock was supposed to fit up to size 14 but I couldn't even get it on my foot. It was way too short. Ended up giving them to my wife.

Soft but bulky
2 years ago
These socks are soft but bulky around the heel and toe. I ordered the size to match my shoe size. It was too large, so the bulk at the toe was not only uncomfortable, but made my boots tight. I ordered on-line with a sale price. It would have cost more to return and reorder, so I gave them to my husband.
