Rated 2 out of 5 by from WARNING: Not the same socks. I loved the previous version of these socks--the one advertised on this page--but SmartWool has raised their prices is the worst possible way: by making inferior quality products. The REI description described the previous version with 71% wool and so I ordered a bunch. However, I received the newer version that has only 61% wool. They look and feel inferior and I am returning them. Looking on SmartWool's web site, it seems that the wool content has been cut for many of the socks I have bought. Time to find a new brand--one that is willing to make actual "wool" socks.

Rated 5 out of 5 by from Excellent all around sock! This is a great everyday sock; does not look wooly like a hiker, but with the padded sole it is very comfortable and seems to have a wide temperature range.

Rated 3 out of 5 by from These socks have changed over the years The quality and thickness of these socks has changed in the past few years. Also REI discontinued their own wool/mix causal socks. They were a good alternative to smart wool. Not why REI stopped offering them.

Rated 5 out of 5 by from Bus Operator I really enjoy the comfort of these socks! They allow my feet to breath and not sweat so much during my daily usage as a bus operator. Highly recommend them!

Rated 4 out of 5 by from Good quality hiking sock Loved the sock. Wicks well so my feet stay dry. Only complaint is the sizing; I got a large, which is indicated for my 10.5 feet. When I buy my next pair, I will try the XL, as after multiple washings (with no dryer use) the socks seem to be tighter. I thing the XL will fit better after multiple uses.

Rated 5 out of 5 by from My son's favorite socks. It had become a tradition in our family that we buy REI smart wool socks for our son. Every year he opens them, he'll say "Yes!" I highly recommend these socks for the men in your family.

Rated 5 out of 5 by from Great everyday work sock I have to wear boots every day, and this is a great sock for that. Medium cushion, medium calf height. Just a great all-around sock. I'll be getting more.

Rated 5 out of 5 by from Good cushioning, breathability. Great socks. Run true to size. I wear size 12 in Nike, Vasquez, and most shoes. The XL fits well. Really like these. Work for hiking or work.

Is there elastic at the top of these sox?

Asked by: dcmimi
There is not an elastic band specifically at the top of the Heathered Rib Socks, b ut the fabric is 2% elastane which provides a good amount of stretch.
