Wear Daily Hunt or Work 10/1/2018

I never thought I'd like over the calf socks, but I received 4 sets of these last year and I can't keep them washed fast enough. I need to order a couple more pair. I wear these for work/duty and hunting. I can get two days wear per sock without athletes foot. Something I can't do with any other sock.


How it fits
I have size 10-11 feet. L/XL fit a bit big, but I smaller calves. Regular human size calved people will be spot on.

Great early season sock 9/7/2018

I use this sock for early season, Kentucky whitetails. The fabric light enough to keep my feet cool but durable enough to tolerate the slippage associated with rubber boots. When I do wear leather boots, the over-the-calf design helps keep the ticks and chiggers at bay.

Great Pair of Socks 9/2/2018

These are a really solid pair of hunting socks. They are very comfortable and warm, while still allowing enough breathability within your boot to prevent excess sweat build-up when doing intense or long distance hikes.

Great Socks 8/31/2018

I used these socks mostly outdoors but I do not hesitate to wear them at work. Very comfortable. Does not retain water and smell like cotton. I do not use cotton socks anymore.
These pairs last 2 or 3 times longer. So they are cheaper in the long run.

"Go To" Sock 8/31/2018

These socks are super comfortable. They are soft on your feet and don't creep down your calf like other wool socks. That has been my biggest pet peeve when it comes to socks. These socks stay put and do a good job of wicking sweat away from your feet.


How it fits
Fit was good for me. I purchased a L/XL and wear a size 11-12 boot.

These ain't your grandpas wool socks 8/30/2018

The Triad sock is a quality piece of gear, they sport a soft, but durable fit. I don't love the length of the socks - going up to the knee - but wearing them with a pair of the boxer briefs covers almost the entirety of the leg without donning a pair of thermals, so there is some benefit. If you wear a lower hiking style book, you could also look at the crew sock.

Great All Purpose Socks 8/30/2018

I use a lot of smart wool socks, these are right on par with smart wool. I love the compression support on the arch and calf area. I hiked/ hunted a lot in these socks over this last year and they are holding up great. I expect these will last a long time. Wool is the best material for socks, hot or cold. These would have been perfect for wild land firefighting. I wish I would have had a few pair 3 years ago.

If you like taller socks, these are excellent. They stay in place and do not sag down.

Wear them every time they are clean! 8/30/2018

I have been pleasantly surprised with how durable these socks are and how well they stay in place. These are tall enough to get over my calves and tight enough to stay there without cutting off circulation. I have owned them for about a year and wore them weekly and put some miles on them they look like they will hold up for a few more years at least.


How it fits
A little tight to get the heal of my foot past the ankle construction but I think that's what holds it in place and prevents my boot from eating the sock.

Perfect wader socks 8/30/2018

I've mostly used these as my booted wader socks. They've kept me feet warm and dry. Since they are taller socks they've kept my shins from chafing and helped my feet stay dry during the high exertion hikes in and out of the blind. I've loved them and I'd recommend them to anyone.


How it fits
Very tall socks covering my entire calf. They stop just before my knee cap and stay up very well.

Awesome! 8/29/2018

These socks are a great all around sock. The elastic band at the ankle keeps them where they need to be, and the tall height is great for not slipping down. They breath well and have good cushion on the bottom. I wish I had more pairs.

500 miles! 8/29/2018

To quote the great Scottish band, The Proclaimers, I would walk... 500 miles... in these freaking socks.

I’ve always considered the foot, the most important part of the body when climbing, skiing, hiking, and hunting. Always spent the money on the quality. These are hands down the best socks I’ve had the pleasure of wearing. I now where them in every sport I take part in. Thanks Firstlite!!

New Favorite Sock 8/29/2018

I would say this sock is my favorite piece of First Lite gear that I own, my wife bought me a pair for Christmas and I have used them for hiking in July, elk hunting in September, deer hunting in November and bass fishing in January. I have tried all of First Lite's socks and these are definitely the best, my feet tend to sweat a lot and when I wear their cold weather socks my feet sweat and get cold, but these are lightweight and comfortable, I never had any trouble with blisters and they actually keep my feet warmer in cold weather than the cold weather socks do. Try a pair, you won't regret it!

Worth every penny!! 8/29/2018

I picked these up for a Spring pig hunt in Central California. After 3 days, 16 miles hikes/crawled these things held up and never irritated! I am blown away by how comfortable I was that weekend with temperatures ranging from 40º-97º. I was actually really surprised with how well they wicked and how they really controlled odor. I rinsed them off with fresh water every night and by morning they seemed brand new.

Fistlires Merino is some amazing stuff. I’ve had merino sock from quite a few other companies but these are by far the most comfortable for early season stuff. They are also thin enough that I use them as a base layer sock when doubling up. They don’t stink either.

These socks are money! 8/19/2018

Super Comfortable 8/2/2018

I'm always nervous about new socks, especially for summer use in the mountains. I asked the CS rep about these and if I would need sock liners to pair with them, I never leave the house without sock liners. She suggested I try these sock as they are, and they were awesome. They kept my feet fairly dry and I never felt any slipping around and I was not wearing sock liners. I logged about 50 miles in 4 days with one pair of socks and they were perfect. Just air them out every night and they will perform every time! I'm buying three more pairs now.

I've been wearing these around the house, on long hikes and while donning waders for fishing and they are great. These reach almost to my knee, which I like; they stay up and they stay dry.

They say merino makes all the difference... 1/11/2018

It's not just any merino, quality matters. Not all merino wool is created equal. This summer I participated in a Fly Fishing event that took us to backcountry waters all over Colorado. I had a new pair of the Mtn Athlete Triad socks, along with other merino brands. The difference between them was night and day. The First Lite Mtn Athlete Triad socks were comfortable, durable, better at managing moisture in my boots, and they remained significantly more comfortable by the end of a long day. After that experience, I replaced my old wool socks with First Lite merino wool socks before hunting season. Now after a full season of hunting on these socks, I'm totally sold. From elk in Montana, to pronghorn in Wyoming, to mule deer in Colorado and Texas, these are my new go-to hunting socks.

Best Socks I've Ever Worn 1/2/2018

I've never been one to pay much attention to socks, until now! Wore these for my first horn hunting expedition of the year and my feet never felt better. Socks were comfy, fit well, and did a good job regulating the temperature within my boots. I'm now a believer!

warm-comfy 12/3/2017

I had my boots stretched and re-soled and forgot to reapply my Obenauf's so when I stepped out of my raft into the freezing river to head to my stand my feet was instantly soaked. I was pissed as my thought was "damn, I just wasted this entire trip and have to bail" ,I was wrong!!!! I took off my boots and dumped the water and wrung out my socks then put everything back on fast as it was only 24F at the time. My feet was toasty warm in no time and I was very happy and stayed and hunted all day-wet boots but warm feet thanks to these socks.

Great Sock 11/3/2017

These socks are fantastic for a couple of reasons. They are tall enough to get over the calf muscle and stay up. This is important when wearing other layers of clothes because you won't have pull them up every time you stop. Another great feature is the lack of hot spots when wearing them. They are sturdy, but not bulky. They are warm when needed and don't get too hot. Cannot recommend them enough.

Good sock, but... 8/24/2017

As with all FL gear construction and feel are great, really want to use them... BUT, I ordered a Large and they are not large enough. The package the socks come in say L=9-12 but the website doesn't clarify sizing for socks, normally this isn't likely a problem for all you normal people, but I have Shideshow-Bob feet (sz16). needless to say my big feet are well beyond that size range. I tried them on, they fit OK but I'm pretty certain they'll prove too small and result in some blisters. I'll likely be returning them for more First Lite gear!

Overlooked piece of gear! 8/21/2017

This sock is awesome! I picked these up on a sale thinking that I would give a good pair of socks a try. Glad I did that. I get really hot, sweaty feet.

Never leave home without them...literally 3/16/2017

Purchased these last season and will never leave home without them again. Literally, I love these so much that I wear them to work sometimes (and I work in an office). Breathe very well and have the perfect fit...these have never stretched out or fallen down. The merino wool essentially makes these scent free in my opinion (though when you take them off in the tent at night before bed watch out! ha). Buy these now if you haven't already - no regrets.

Underrated 9/19/2016

Socks were never something I thought too much about, until I tried these. I thought fatigued feet and cold toes were a norm. Not with a quality pair such as the Mountain Athletes. A lot of foot support comes from these socks. And the warmth and comfort from these will change your day. My feet were noticeably less tired, and my toes stayed warm through wet and below freezing temperatures. Took them off and put them in the sun in midday and they were dry in 15 minutes. I can’t believe I used to wear sub-par socks. Never again.

Best socks around 8/30/2016

I hiked in these dudes three days for a total of 22 miles at 11000' and my feet never got so much as a hot spot. The old merino socks I used to wear would give me some solid blisters after just one day. Very very comfortable and they stay in place- no sagging

Underrated piece of gear... 8/20/2016

These are the most comfortable pair of socks I have worn. Underwear and socks are an overlooked piece of gear for many hunters/hikers, but the designers at First Lite nailed it on the Triads! Super comfy and they don't break down after a hard day in the boots. Both the Triad and Compression socks seem to be holding up well, but the Triads remains my favorite...

Worth it 8/8/2016

Don't be phased by the price. These socks are great. I have worn them a lot with my snake boots to keep them from rubbing and they are awesome. The wool is great because they can keep your feet really warm and absorb the sweat when it gets hotter. These socks will have you wearing them days in a row. Super comfortable and worth it.

Absolutely Incredible! 2/23/2016

Extremely comfortable, and incredibly durable; I've pretty much lived in two pairs between August and mid-January, hunting, and running hunts, from the mountains of Colorado, to the hills of AZ, to the river bottoms of KS, and they are STILL in great shape! I've washed them countless times, and worn them for weeks at a time (alternating between the two pairs) without washing, and they still look almost new, and still stay up 95+% of the time. My feet don't stink, I've had zero hot-spots, and no noticeable thread-wear so far. WELL worth the money.
