SmartWool PhD Ski Ultra Light Sock

My staple sock for any cold-weather activities. If you like thin and warm, this is perfect. I first got them to go with some particularly snug ski boots, but they are thin and comfortable enough that I even use them for winter trail running.

%-Star is right. Low volume sock that allows me to really feel my insole and boot. I have always loved really thin ski socks, and now that I can wear thin wool socks it's even better. Great wicking for long BC tours. Nothing like putting on a brand new pair, so get a few!

These socks are amazing. They are so comfy and keep my feet warm and dry.
The reason thin socks keep your feet warmer than thick socks (or two pairs of socks) is because the thin sock will wick away more moisture from your foot. when there is moisture in your boot, it makes your feet cold. thin socks prevent this.
I can wear these in my stinky sneakers for 3 days straight with no stink. I hand wash them (I don't have a laundry machine so this is faster, but I machine wash them when I do laundry) and they are dry within a few hours. I have one pair, but I wish I had a lot of them so I can wear them everyday.

Paired these with a new pair of Lange Super Blasters. First pair of really thin socks. Have definitely helped during the break in period. Keep my feet warm and allow me to feel the boot. Won't be going back to a padded sock.

super long lasting... my last set lasted 4 years! outstanding for such a thin sock... great fit and warmer than you would think... plus an all natural fiber which is sustainable... another plus

Finally, a ski sock that is wool and thin / low volume. I have tried many many thin poly socks, all more expensive then this smart wool offering. This is no doubt my favorite ski sock. Since getting it I have not worn another sock for skiing. Warm, moisture wicking wool and nice and thin so I can wiggle my toes with ease in my at boots.

I actually prefer the lightweight sock with extra padding in the heel and shins, because it helps prevent shin bang and also hold my heel inside the boot better. For me the best part is wearing a lightweight sock inside my boots, because the thinner the sock the better for my feet. It doesn't strangle your feet and allows for good blood circulation when your boots are cranked down tight. Smartwool makes a great product.

Exactly what a ski sock should be - thin, dry, warm, stink resistant, non snagging. Nice touch: they stich the abbreviation for the size into the cuff, so my LGs can be distinguished from my wife's MDs.

Very thin, just like your second skin.
Very smooth and stretchy material, feels more like a lycra not the wool, and it doesn't matter how long you're wearing it - every time it's snug on your foot without folds and wrinkles. Even when wet.
There is no stupid branding or X-men-like padding thankfully.
Pretty durable, one season in one pair and still on duty
(but care your fingernails regularly).
And yes, after all it smells like flowers, not like my feet.

Search mission complete and I just remembered my size (fits true to size), and hope that Smartwool will do it eternally

I ordered 3 pairs because these were exactly what I wanted. First pair was perfect. GREAT weight in my ski boot. Second pair one sock was 3 inches shorter than the other? Hm, a childrens maybe, but the foot fit right! Third pair were fine.

I can deal with it but I didn't read they were seconds and they were too expensive if that's the case.

5 Stars because they are perfect - someone just got crazy when packaging them!

Switched from bulky, heavy ski socks to thin liners years ago. Will never go back.

These socks are the best I've used yet. They perform exactly as advertised.

Sizing SmartWool socks of this type, thin liners, is problematic for me. According to SmartWool's sizing guide I should wear a large, but they are too large, even after washing and drying. Mediums just barely fit. Bought mediums this time and will try air-drying instead of tossing in the dryer to see whether that results in the perfect fit.

These are my new favorite ski socks, they wick well, dry fast, and keep you warm in most New England ski conditions. Only time I switched to something else was when the temp dropped to 1 F (-30 with wind chill) and I used a heavier wool sock from icebreaker.

These are now my go to socks for the vast majority of my snow time.

Tested in temps from 10 F to 40 F, happy :)

I started out the day with a far to heavey ski sock. My foot was loosing circulation. So i headed into the pro shop and asked for a recommendation. He said the PSIA was in the other day and bought all of the these socks and he just go more in. So i bought a pair. They are very thin yet kept my feet warm in 20 degree weather. My boots fit great and i was even able to tighten them a bit. I liked them so much i bought 2 more pairs a day later.

i bought three pairs and returned them all after one got holes. they felt great and i like the height, but just not durable.

These socks are very good. They are lightweight and thin so that you stay comfortable in your boot along with being able to feel around your boot. Although they are lightweight and thin, they are still warm and protective. Awesome in all conditions and temperatures from cold powder days to spring skiing.

I've never had anything smartwool that wasn't great. Decided to try these as winter dress socks for the office. I'm really pleased.

This is the only sock I wear to ski. Super warm, paper thin, moisture wicking, and smell resistant thanks to the organic merino wool. I have tried other socks and they aren't as warm and STANK. If you have custom fitted boots, do your feet the favor of wearing these socks.

This is the ONLY sock I wear to ride. Super thin, super warm, super comfy. They don't stink after a day on the mountain either, thanks to the merino wool. Basically, if you have custom fitted boots do yourself the service of getting these socks. Your boots will never fit better.

Great socks for cold weather. Wore them in below zero temps. Didn't give them a 5 because they were too warm for me despite their thinness and antipersperant. Try 'em out. Price is right and quality is great.
