Smartwool was founded in 1994 in Colorado and have been making socks in the United States with wool from New Zealand and Uruguay ever since.  The socks are actually manufactured in plants in Tennessee and North Carolina.  There is a pretty cool youtube video on the main page of their website on under the Made in the USA link.  They also have a neat section on the site about their innovation and history of their socks.  Pretty interesting if you like to know more about how socks work.

The PhD Run Ultra Light Low Cut Socks, “socks” from here on out, are exactly what the description says – lightweight running socks. They feature Smartwool’s “4 Degree™ elite fit system, Indestructawool™, a virtually seamless toe and men’s specific mesh ventilation zones.” They are comprised of 49% Merino Wool, 47% Nylon, 4% Elastane according to the website. The Smartwool PhD Ultra Light Low Cut socks retail for $15.95. That covers the technical aspect but the question is how do the socks feel.

When the socks arrived, I immediately put them on and went for a run. The socks are light and very comfortable next to skin with no itching from the wool fabric.  Actually the socks are super soft.  My foot size is a 9 so I am on the small end of the large size range so my foot does not exactly line up with the Indestructawool™,  reinforced area on the heel; this will be an area to watch for durability.  The socks are very thin with minimal cushioning as I expected.  My initial impression is positive.

I will evaluate the socks on the following two main characteristics – comfort and durability. Some of the questions I will look to answer are: Are the Smartwool socks comfortable? Do the socks wick moisture well?  Do the socks keep my feet warm or cool depending on the  conditions? How many miles can I use the Smartwool socks for before they wear out?  Can I wash and dry the socks with my other clothing?

Thank you for reading my initial review – please check back in a month or so to see how the socks performed.

Thanks to and Smartwool for providing the socks for this review.
