Perfect Amount of Cushion

  • Familiarity: I've used it several times

I wore these under some ankle height hiking boots to replace some old "no show" socks that slid off my heels and these were perfect. They were so thin I could barely feel them, but the toe and heel cushioning was perfect. My feet did not get hot or sweaty. SmartWool did a great job on the moisture wicking and temperature regulation. The pattern on top in pretty cute too. So comfy!! They have been through a couple of washes and still feel like new!

SmartWool PhD's earn their name

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: Small

I have had several pair of the SmartWool PhD socks that were the "no show". I decided that for boots I might want a thinner sock and one that will last but goes up a bit higher on my ankle. These fit the bill. Honestly, these last a LONG time. They don't lose their stretch/shape/functionality after many many uses. The threads don't come undone. They are ver well made socks. They keep my feet DRY when the heat turns up from my physical activity. I am excited to put these higher socks to use come fall/winter. Love the colors and designs. Highly recommend!!!
