A techy sock for toes that go fast in the cold.

SmartWool identified impact zones that cause your feet discomfort in ski boots, and in response, it added extra wool to the Women's PhD Ski Medium Sock. This is a cushioned sock designed specifically for alpine skiing or snowboarding. Naturally breathable merino wool regulates temperature, elastic construction provides support, and SmartWool's high-quality construction means ultimate durability—how can you turn it down?

  • Fast-drying nylon and stretchy elastane are combined with merino wool for ultimate comfort
  • Merino wool is non-itchy, naturally breathable, resistant to odor-causing bacteria,
  • 4-Degree Fit System uses elastic construction to provide extra support at the ankle, upper instep, lower instep, and arch band
  • Zones of mesh venting on top of the foot allow hot air to move away from your foot to keep you cool
  • Wow Technology uses double-layer wool on the sole of the forefoot and the heel in order to reduce shock and make this sock more resistant to abrasion

Gave them as a gift

She loves them, although they are a bit thick for her boots.

Great sock!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

A great pair of socks that keep my feet warm in the chilly weather. Soft and very comfortable. My only complaint is that the sock seems to run a little long up the leg -- it covers my entire shin and keeps going well into where my knee bends. Also, I have pretty muscular calves and this sock (like many others) are a big snug in the calf region.

Too tight for my taste

  • Familiarity: I returned this product before using it
  • Fit: Runs small

I ordered these in a size Large because they were on sale, although I generally wear a size Medium/Regular. I ordered the "wine" color, which I believe is no longer available. Generally I like Smart Wool, but I returned these. They were far too tight in the calf area, stretching the pattern to where it looked bad. I also didn't really like the color; it seemed more purple in the photo. Backcountry photos are usually very true to life, but this one was a tad off imo. I would still buy SW and buy from Backcountry in the future- the return was super easy and I kept several other pairs of socks I had ordered for myself and as gifts.

Great socks, like the look and the feel and they have kept my feet pretty warm so far and have used them in about 20 degree temps.

Best ski socks around

These are my favorite socks to ski in, hands down. Super warm, keep my feet dry, material is soft and comfortable to wear all day.

Great socks with extra warmth

as told by my wife: really comfy socks. they stay in place in her boots, keep her feet dry, and she appreciates the padding on the shin. she wears her icebreakers on warmer days and her smartwools on colder days.

Love these socks!

  • Gender: Female
  • Familiarity: I've used it several times

Love these socks! They keep very warm, but at the same time don't let my feet sweat. Although they are wool they don't itch. Perfect for cold weather. No need anymore for 'toe warmers'!

Not just for skiing!

  • Gender: Female
  • Familiarity: I've put it through the wringer

I live in Canada so staying warm is a must and these are my favourite winter sock! I own three pairs and wear them everytime I leave the house:) I don't find them too warm while indoors either. So comfy.

Favorite Ski Socks Ever!

  • Familiarity: I've used it several times

SmartWool rocks

  • Familiarity: I've used it once or twice and have initial impressions

I got these for my wife and she loves them...but then again she loves everything from SmartWool.

medium thick ski sock

  • Gender: Male
  • Familiarity: I gave it as a gift, but have feedback to share

I got these for my wife and they are great ski socks. If you have new ski boots that are still really tight I would recommend the PhD Ski light sock. Once your boots are starting to feel a little loose these are great though.

Love the Colors

I got these in the black and the purple for skiing this season. SmartWool socks are some of my favorites on the slopes and these look like they will be awesome as well.
