Night skiing, anyone?

Unless you've completely blocked it from your memory, you might remember your very first time on skis and the way you felt when you withdrew your pasty, clammy foot from a wet, frozen bunched-up cotton sock. The Smartwool PhD Ski Ultra Light Sock gives you maximum warmth without the bulk and without that horrible clammy wet-cotton feeling you've hopefully managed to erase from your mind.

  • Merino wool blended with nylon and elastane offers exceptional temperature control, flexibility, and support
  • Mernio wool's natural antimicrobial properties keep these socks fresh even if you skip a few washings
  • Merino wool regulates temperature so your body wastes less energy trying to keep you warm or cool
  • ReliaWool tech adds comfort and durability to high-impact areas
  • Mesh ventilation zones get rid of moist, overheated air
  • SmartWool's 4 Degree Elite Fit System uses two elastics for extra flex and compression
  • Compression tech helps energize your feet and prevent swelling

Perfect Ski Sock

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

I can't use anything else to ski in but these ultra thin smartwool socks! For those of you who require a thin sock this fits the bill, there is not any extra padding, cushioning, etc that so many ski/snowboard socks come with. Because they're merino wool they are fairly heat regulating, and I can use them multiple days in a row before they start to get smelly. They're pretty durable too, the few pairs that I've had for a long time (probably 5+ years, and mind you I easily ski over a 100 days a year) have yet to still get any holes in them.
I wear a size medium in these socks and I wear a size 7 women's shoe. I have a pair of these socks in size small too and they're indeed a little too small. So these socks run true to size.

Perfect thickness

  • Fit: True to size

SmartWool is always great. I squeezed these into my AT and alpine boots with no problem and my feet stay happy and warm all day (and night). These socks are also very durable.

Happy Feet

My feet like these socks, a lot. The first time I used these socks was on a 7 hour long, 8+ mile day of Backcountry touring and these things are awesome. When it comes to Backcountry skiing in the early season it sometimes takes a bit to get in the groove of what gear you are going to wear for certain weather/distance conditions. After some time in these socks, I assure you that I will have these socks on my feet for most days. They are warm, light, and full of an abundance of merino. All that makes me want to wear these socks each and every time I tour.

Sweet Sock

  • Familiarity: I've used it several times
  • Fit: True to size

I have worn these socks for a few ski tours and they are great. They wick sweat very well and the thinness makes for a great fit in my boot. I wear a 10.5 size shoe and the large was perfect.

Ultra light= Ultra good!

  • Familiarity: I've put it through the wringer

thinner socks work better for me as opposed to thicker socks and these are my go to pair! I purchased a pair of ultra lights and a pair of mediums..I'll be returning the mediums and getting more ultralights!

The best sock...

... for ski boots, period. Comfortable, lightweight, warm in most conditions and the performance is great, too.

King of Ski Socks

After years of personal use with Smartwools, I finally got the guy some Smartwool ski socks, and he loves them. Again, super comfortable, lightweight, and keeping your feet as happy as it is possible when sitting all day in ski boots. Would definitely recommend these!

Great Ski Sock

However these have a little more padding than the Point6 Ultralight. the P6 is the best in the category IMHO.

Awesome socks

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

I love these socks so much i bought 2 more pairs. My feet fit pretty snug in my boots so a thin sock was what i needed. I highly reccomend these.

Wear them all the time

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

I went down a size in ski boots and the shop suggested I try these socks since they're so thin. I'm glad I did! These socks are AWESOME for skiing, I love the compression and will be buying at least two more pairs for this season.My feet do get kind cold so I wouldn't say they're the warmest socks, but I am a diabetic so that could be the reason for the cold feet...

Warmth and performance

  • Gender: Male

If you like to crank your ski boots down before each run, this sock gives you excellent feel and control on the hill without sacrificing warmth. Not sure where the warmth comes from but its there. I'm a size 13 shoe, ski a 29.5 boot, and I prefer the Large over the XL.

Light and thin

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

I like these. I don't use them for really cold things or in the snow, but they're great for everyday stuff. I have thicker Smartwool socks for snow activities. These might be fine in the snow though, I just haven't tried. I really like them though!

Amazing SKI Socks

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

I picked up a pair of these last season and ended up with 10 more. Recently found them on sale for 10 bucks a pair and loaded up! Use them for skiing. they kick ass! Great padding where its needed!

Disappointed

  • Gender: Male

I swear by smartwool i wont buy anything else. However this is my first pair of ultra lights and i was disappointed. i wore them 3 days hiking and they tore. I know they are made for skiing but i have never had this issue with the light or medium cushion socks. Maybe i got a shoddy pair but i think ill be sticking with some thicker pairs from now on.

Responded on

try the Point 6 Ultralights. They're bomb proof, although not as soft.
