Smart wool socks are expensive, but the warmest socks ever.I ordered these from discount on line store and were poor quality. These are what I was looking for! Warm and durable. Extremely happy!

Meant for diverse activity...
April 07, 2013

To ride my gaited paso fino in top form I do hip hop, zumba, and body sculpting fitness classes. These light weight SmartWool socks have left my feet feeling drier, not sweaty at all in each one of those classes throughout the week. The outstanding wicking property is really needed in this hot, desert environment. I'd only buy SmartWool.

Best socks for everyday
July 10, 2013

Smartwool makes the best socks and the PhD run is tops. I'm not running so much these days but wear them for everyday use (lots of city walking) with sneakers. They maintain their shape, keep my feet cool and dry, and don't stink at the end of the day! I can even wear them a few days in a row, making them great for travel when laundry options are limited. The cushioning is just the right amount. I was a Thorlo devotee - don't tell them but I think I found a new sock to love.

Pros: Great design, Build quality, Lasts forever, Performance, Ease of use

I train and run half marathons and these are the only socks I will wear on my long run and race days. They have the perfect amount of cushion while still being breathable enough for wearing in the middle of summer. I have bought several pairs but the original pair I bought several years ago is still just as great as the day I bought it!

Pros: Build quality, Lasts forever, Great value
