I bought 9 pairs of these in 3 different colors. They're absolutely amazing, they breathe well, are comfortable and also don't get that funk that other socks do. I wear them as a casual sock and also when working out. I'll never buy any other socks. Purchasing more as we speak!

I used these for several road races and logged many training miles on these this year and they kept my feet cool, dry, and comfy. Also you can feel the extra cushion in the heel and ball of the foot...very nice. I wear a size 10.5 shoe but decided to get the S/M, and it was a great decision. They fit perfectly.

The pricing on these socks is killer. And they look great, and run really well. They fit well, are nicely elasticated, seem durable (so far). BUT they do seem to get smellier quicker than my other socks. As long as you put them on to run, and take them off afterwards, you'll be fine. But I can't really recommend them for all day use. :-(

I use these socks for running and have no complaints about them. I have used them every time I have gone running through the summer and fall. Contrary to what others have mentioned, none of mine have gotten holes or have fallen apart in anyway. I also haven't noticed any stench.

The sizing is true, they are comfortable, the price is good, i will get more.

I'm a fan of these socks. For the money, you won't find another three-pack that fits or supports your foot this well. I like the strategic zoning, since I get blisters easily through thin socks, but I don't want a heavy sock either. The only negative I am predicting is that somehow, I will end up pulling 6 Left socks out of the dryer, with no Right socks to be found anywhere.

They feel pretty comfortable, but the strategic placement of material is a kinda overkill. Also felt a little slippery in my shoes too, which I think is from all of the different fabrics. They do breathe super well, and they're ugly as sin which I like since your socks get trashed on the trails anyway.

I use them for cycling because they don't feel mushy like other socks in the bike shoe. They are a little thin, so hopefully they don't get holes in them too soon. They also have a design on them that indicates which foot it goes on (R/L) which I thought was funny. I wish they came in a no-show cycling version.

The SynthTrail Crew Sock fits my foot very well and the "breathability" is excellent. They do not provide much padding or extra cushion so make sure your shoe is a tight fit. If you have space in your shoe your foot will slide. I have used these with the KEEN Targhee 2 Mid Hiking Shoe. The socks are okay with this combination. I usually use Smartwool or Bridgedale socks with great results. The SynthTrail is incredibly thin and tends to slide around in the shoe. I would recommend these for a tighter trail running shoe rather than a hiking shoe.

Love these...Great deal, move in the shoe well (I like a snug shoe and a little more slip between the sock and shoe)...they're warm, but breathe well so not to get foot rot...and I love the non standard colors with the goat logo on the heal. Definitely beat the heck outta my wigwams

Very comfortable socks. Lately most of the socks that have any cushion seem to be too thick. These socks are both thin and supportive. I love the blue.

My Montrails are size 10 so I went with the L/XL, but due to the tongueless design of the shoe, they're a little tight when I'm putting my foot in. These socks run a little large, so the heel gets pulled back when I'm putting my shoes. I can get it to fit with no wrinkles but I wish I had gone with the smaller size. Nice thin socks, great feel around the foot, love the asymmetric design.

I use these socks as an inner sock to a thick wool sock for hiking. My last trip left me with wet feet for two days, and no blisters. Plus, you know your big time when your socks are made for a left & right foot...

Great feeling sock and gives great support (yes even though it's a sock). Doesn't wick as well as a wool sock but still does a good job

I picked up a couple 3 packs of these on clearance a while back not expecting too much. These things are amazingly comfortable. I tend to have sweaty feet but not in these babies. I stay comfortable and dry. Its hard to notice i have socks on when i am wearing them. No need to look any further.....

I'll use these biking,hiking and just traveling around. They are super comfy and keep my feet warm and dry. I'm yet to try a bad backcountry sock.

these socks are amazing for biking around town in

comfy feet are important on the trail, these get it done.

...But the best part is mismatching them!
They're cheap enough you can buy 2 sets and mismatch the colors all you want. I actually bought 3 sets, because I'm really into mismatching different colors of the same thing.

One Obnoxious Downside: These things pick up hair and fuzz like few other socks I've had, and it'll stick on the sock through the wash. My house is infested with dogs, so I don't wear these unless I'm headed out the door or in shoes. :)

These socks are comfortable and fit nicely without any bunching. However, be careful when pulling them on. I stuck my thumb right through the goat pulling them on. Now I have a big hole in the back of my one sock.

These socks are the perfect weight for any short hikes and for wearing while doing anything. They also double as a great undersock for construction

Good sock with extra thickness in places with the most wear while walking. It is thin and lightweight. It wicks sweat well from my experience. It will slide a little in your boot because it's thinner than other hiking socks but I haven't gotten any blisters from it yet. Anyway, it's a good sock.

Very comfortable and breathable, highly recommend, just look goofy.

they are comfortable and hold up well no matter what the activity. Cycling, hiking,etc.

I think these socks are an excellent short sock for a variety of activities. I have worn them around the office and on a series of day hikes. They can be a little warm for my feet when inactive, which surprised me, but they were very comfy on the hikes and I would recomend them. PS I got them on sale, which makes them even better.

These are solid. They're comfortable hiking for a while, but they do smell after a while. Not too bad, though. Get the socks. The non-padded areas are very thin, though, so they're not cold weather socks.

I will definitely purchase these socks again.....I do work for backcountry but I'm not biased....my feet sweat on good hikes and these socks kept my feet dry and cool.....WILL ABSOLUTELY GET AGAIN!

These socks are cool. For those of us who love backcountry.com what better way to show your support? I wouldn't wear these with hiking boots but for hiking, climbing, really any sue theya re comfy, thin and styling. They do get a bit warm for their thickness but that is the only downside. Also we bought 2 pairs (3 pairs each) for $9.99 on an awesome BC sale. I would not pay $25 for 3, $10 was a good deal.

Love these! Used them in new boots on a A.T hike and they were amazing. Kept my feet dry and comfortable. Only complaint is they were a little big.

I've been loving these on my daily runs, then I used them on a 12 hour adventure race and liked them even more. Only changed socks once all day, feet were wet all day, no blisters or hot spots at all!

These socks are perfect for my feet besides loving to hike. I'm on my feet most of the day at work. They're so light and cool and the padding in all the right places. I had to go back and get some for working. I can really tell the difference and the end of the day. Try them.

Cheap(price), comfy, wicking and stylish(in an outdoor gear way). They have lasted through long hikes and tough approaches, dont stink and fit very well. My $.02- Buy em'. Oh, and they are labled L and R in case you had too many after adventure beers!! lol

These are average. I use them for cycling, but they feel like they will be worn through in a few rides. They are also piling after 1 use.

Great socks. 5 stars for me. Light, comfy, soft, breathable. I will be back for more...

These socks aren't bad. They're pretty thin, especially in certain areas. That works well to keep your feet from getting too hot/sweaty, but it seems like it might shorten the life span of the socks. Time will tell I guess. The synthetic material does tend to pick up a lot of hair and stuff, so it may not be the thing to wear around the house if you have a lot of pets or shedding rugs. I like how they feel when you put them on - supportive and snug - but as other people have said, they do kind of slide around in your shoes, especially if the shoes are smooth on the inside.

I bought a pack for my boyfriend to use biking and he got holes in them on the first use (at least 2 of the three pairs). I don't know if there is something going on in his shoes, or if he was man-handling them, or if he just got a lemon pack... but unfortunately they did not work out.

I mountain bike in these and they generally do a good job of keeping my feet cool and dry. Would love to see a broader range in size as L/XL is a little roomier than I'd like for a size 10 foot...may be a little too thin when the weather drops, so planing on it being a summer sock.

These are great form fitting socks. The are comfortable and they are a great deal. They are a bit slick in your shoe, but that's what this type of sock does. I wouldn't wear them in hiking boots. I'd use wool socks for that. These are great for my tight fitting bike shoes and I wear them for running too.

They got the padding right and I like the fit. They are on the thin side and are a little slippery inside in my shoe. My foot slides a bit when I'm hiking. My feet got hotter than with cotton socks.
