Mesh zones on top sections of the Smartwool PhD Outdoor Ultra Light Mini Sock mean your foot can breathe while you hike in hot weather, and the wool-on-wool technology reduces shock so the bottom of your foot doesn’t feel like a jackhammer after a few miles. Since wool naturally fights odor, you can wear this sock on weeklong backpacking trips without fainting when you crawl into the tent at night.

Bottom Line: Take the heat.

Talk shop with all the gear freaks out there: ask 'em questions, upload/browse photos, and give your 2¢.

Holy Crap, these socks!!!

By:
3 days ago

I bought a pair of these on sale and thought "Hey, I'll try them out maybe they'll be okay." Then I got them and spent a day hiking in them. Holy crap, these socks, guys, these socks are awesome! I liked them so much when I got back home I immediately ordered 1 more pair of each color.

They're pretty solid socks. Good cushioning on the bottom and nice and cool on top. I hope the hold up well, because that's ultimately the measure of a great sock in my opinion.

My son lives in Fairbanks, Alaska and wants Smartwool mini socks.

My son lives in Fairbanks, Alaska and wants Smartwool mini socks. All the reviews I've read say they are for warm summer weather. Does Smartwool make a mini (ankle high) sock for winter?

Both these and the PHD Outdoor Light would be fine for summers in Fairbanks.

Actually they do make a heavier low cut socks because I own a pair. They are called the Smartwool Hike Medium Mini Crew socks. I'm not sure how well it would do for Alaska weather but mine do pretty well for winters in Western NC.

I don't think they make what you're looking for. Having a thick, warm sock with exposed ankles is kind of self-defeating.

Smartwool Rules!

By:
October 1, 2010

I wasn't going to review these socks, because who really needs a sock review, right? However, these socks, the SmartWool PhD Outdoor Light Mini Sock, and the Teko Merino socks are my go-to socks for workouts, hiking, backpacking, and hanging out. They have never failed me, and I am able to use them for multi-day trips without changing them. I just wanted to pass on my satisfaction with these. I haven't had the durability issues others have, but your mileage may vary. I would recommend them.

Nice and warm. They are doing a nice job of helping me through the Minnesota Winter. A little bit expensive, but worth it.

Sockem!

By:

Best socks I have owned period. I absolutely love these things, I use them for everything from mt biking, hiking, running, workouts etc. They are lightweight, breathable, and I personally have yet to find a good smartwool sock that can fight odor as well as these. I have used them for biking in wet/muddy terrain, dried them in the sun, turned around and hiked 15 miles the next day in the heat, packed them out to camp, and wore them a day later in the rain again, still no odor. Serious socks for serious people.

The Right Weight

By:

There are a lot of summer running socks out there. These socks are comfortable (mostly wool) and are the proper thickness for comfort for both long and short runs.

Great sock

By:
April 25, 2009

I think this is the right kind of ultralight that I got. It's a great sock, suitable for many uses (hiking, biking, everyday wear, etc). They fit really snugly.
They make some fuzz, I would say, with washing, but it's not bad. Don't throw them in the dryer though!!!

So Comfortable

By: Backcountry.com Employee

The moment I put these on, they were the most comfortable socks I had ever worn. They have been great for hiking during less than hot/cold conditions. Perfect for fall and spring. I really like the support zone around the arch.

These are great for running, hiking or daily wear here in the sub-tropics, even in the summer. My feet are wide, square, and high volumne. Another great hiking sock from smartwool.

Best Socks EVER

By:
February 16, 2012

I love these socks, sooo comfy, with support in all the right places. People think I'm crazy when I go on about these socks, once you own a pair you know what I mean. They are just the right thickness, not too warm in the summer, but warm enough for the winter time. I own 5 pairs now, and working on replacing all my other socks with these, I usually buy a pair or two every time I order something from backcountry.

This sock has great cushioning and is extremely comfortable. They are durable and have lasted longer than comparable socks from other manufacturers (e.g. patagonia, keen). they still maintain their softness even after repeated hand-washing and line-drying.

Love these socks

By:
October 7, 2009

These are my favorite socks for just about everything. They are super-comfortable and perform especially well when hiking and working outside. They prevent blisters and are breathable and dry quickly if they should get wet. I wear them with boots or shoes. Contrary to other reviews they are machine washable/dryable. My only complaint is that they tend to wear out and get holes in the heel after 6 months to a year. I put them through a lot of abuse though so I still happily buy more.

nice mix

By:
August 13, 2009

Great for warm weather hiking (or all year round if your feet stay hot like mine). These socks are long enough to peak out from my boots above my ankle but stay low enough to keep me clear of Squaresville.

I would definitely recommend them for any activity with a boot - no stench, plenty of comfort + support.

Perfect every day socks!

Whenever I go to the sock drawer I'm HOPING to find these. Out of all the wool/wool-blend socks I own, these are most comfortable, durable, and odor-free. Have had no shrinkage issues with normal laundering either. Doesn't get any better.

Really takes care of the feet. Really good cushioning and support against blisters. The most opposite of cotton kills.
