Rated 5 out of 5 by from Comfy Toes! Despite the adage that 'cotton is rotten', I've always been a devotee to cotton socks. They're soft and cozy feet always give out. After discovering REI Garage I decided to give Merino wool a try as everyone I hiked with swore by the miracle fabric. I was not to be disappointed. The REI socks were perfect. The price was great and the fit was wonderful. After hiking up El Cajon Mountain in new boots I can attest to the fact that these sock held up great. My feet never hurt and remained dry throughout the long ordeal to the summit of El Cajon. After washing the socks held their shape and look like brand new. Great socks!

Rated 5 out of 5 by from Great buy! I own one pair currently and will be purchasing another. I am also going to try the thicker hiker because my feet still get cold sometimes. I have worn these on an easy snowshoe trip and they were great. I also have a couple of pairs of smartwool hikers and I really like the fit of the REI socks better. I feel that the Smartwools have extra material at the toe which bunches and the REI socks fit better in the toe but also the arch. Plus the REI socks are less expensive.

Rated 4 out of 5 by from Great sock for winter I bought these to wear in my house during winter. They are very cushy, but stretch out after 2 days of wear (I wear them inside my slippers, or as a slipper-alternative). They do start to pill after one wash, but the shape comes back, and the cushy-ness stays too. They are a bit bulky for athletic shoes, but work great in snowboots. I got the maroon ones, and they are true maroon, not as pink as in the picture online.

Rated 4 out of 5 by from Have to try a bit longer bought these to hike a 500 mile trek in Spain and so far they feel soft, they are not too thick which is what a wanted, they fit well, and they do not keep the sweat in the feet. I feel, however, that my big toe (longest) is already thining the material from just hiking three times. I will keep one pair and continue trying to see if they hold bcause they are very comfortable and the right height for hiking shoes.

Rated 5 out of 5 by from love these socks! I love these socks. I am always cold, so my two pairs really get a workout during the winter. I wear them out and about as often as I can. They are a bit too bulky to fit in my athletic shoes, but that's to be expected. Also, they hold up for several wears between washings. I'm buying more this winter.

Rated 5 out of 5 by from So comfy and warm I love love love these socks. I was gifted a pair from a friend in my earlier years in college, and I haven't looked back since. These socks are warm, comfy, and they don't bunch up like some of my other heavy socks do. My feet tend to get very cold in the winter even in boots, and these socks help a lot.

Rated 3 out of 5 by from Warm and a bit bulky I find these too bulky around the toes and arch for me to wear them athletic shoes/hiking boots. Although they're "light" there is still a lot of padding and cushion in them, which just doesn't work out for my wide, high-arch, high-volume feet. I do wear them around the house when it's cold out and I love them for that. They're very soft and cozy, even after washing.

Rated 4 out of 5 by from Softer than Smart Wool Socks I have always purchased Smart Wool socks, but recently purchased the REI socks instead to try out. The REI socks are much softer and I even think warmer. I wear these socks everyday to work to keep my feet warm.
