These socks are the best--the contouring that comes with the PhD setup is extremely comfortable. Makes your foot feel really well supported throughout the day. The socks are comfortable--warm enough without being hot; thin enough to be worn with most any shoes but still toasty. I wear these as often as I can.
These socks are awesome! I got them for hiking the AT. When I first got them you could tell they were quality made. The heel and toe area have extra cusion for impact and the sock fits tight around the ankle to keep the sock from sliding. I love to just wear these socks everywhere I go. I wear a size 11-11.5 and got the Large and they fit great!
"warm, durable, and keep the blisters off my heels"
I have been using Smartwool PhD socks for a year now for hiking. Nothing has made my feet happier. The thicker heel and toe keep the blisters away while the the thinner middle section doesn't add so much bulk over the top of my feet. I have tried the whole super thin sock thing. It just did not make me happy. These are a good compromise with extra padding where it helps and less bulk than typical wool socks.
I was a little hesitant about jumping into Smartwool socks, mostly due to the high price tag. Let me tell you though, you get what you pay for. The PhD line is awesome, and leaves your toes feeling super warm on cold winter mornings. Fit is great and the socks seem very well constructed. Don't kid yourself with cheaper wool socks, they don't compare. I highly recommend these!
"It's just a sock? Hardly. Will not hike without them ever again!"
These socks were incredibly comfortable right out of the packaging for a hike to the summit of Mt. Marcy in NY. Extremely breathable meaning that despite their thickness, I never once felt overheated in them despite the high temperatures of the day we went. Several mud/water puddles later, these socks combined with my trail shoes kept the feet nice and dry. After approximately 16 miles roundtrip with moderate elevation gain, I never felt any slipping and did not develop any blisters. Honestly, if I weren't actively assessing the quality of the sock while on the hike, I never would have noticed they were on, they are that unobtrusive and protective of the feet.Have used them on several more hikes- they remain as comfortable as day one. Washing and drying has not done any damage to the sole, so they seem like they'll have a long life.My wife blew a gasket when she found out I had spent this much on 1 pair of socks - but after a single use I cannot imagine using anything else
