I've used Wrightsocks purchased at REI for over 10 years. The early versions were good, but the current Ultra Thin Quarter socks are their best offering. My feet tend to swell during warm temperatures. The double layer version works well, but the Ultra Thin Quarter socks work even better to keep my feet cool. I don't experience the same problem with swollen feet. I highly recommend them.

Ultra Thin Quarter Socks

Comfortable and hopefully long lasting

great sock - I love a thin sock and this is a perfect as it gets. I'm right on the size line (between a size small and a size medium). the size down felt too small - so I tried a size up which gets a bit slippery. So I'm back to the smaller size. they wash well and so far have held up. I'd love it if they came in more colors.

As advertised. They met my needs for fitting with a specific pair of walking shoes
