Great socks

These socks had the right amount of cushion for toes and heels, but not thick in the middle. I used them biking and they were just right! Good price too.

Great service.
Yes , I recommend this product
I needed some more hiking socks and live in the Pacific Northwest and shop regularly at REI, but visiting family in the Midwest. The store was a little smaller but still had the essential gear needed for any adventure, and the costumer service was excellent as well.

Comfort fit, perfect match for my low hikers
I needed a pair of socks to wear while trying on boots so i grabbed these off the rack and put them on (after promising the salesman i would pay for them). Glad i did. They fit well and were comfortable for walking around all day.

These socks are super soft and the moisture wicking is great for long hikes. They are comfortable in any shoe I choose to wear. I ended up buying 3 total pairs because of how much I loved them.
