I haven't noticed the toe seam, so that could be a foot shape/shoe issue, not sure. Hands down the best socks I have ever run in. I wore a pair for a 100 mile ultra and it's the first time I didn't get any blisters. Even with wet feet after a river crossing. Not only are they comfy, they last for a very long time. I have over 300 miles on a pair and they show no signs of wearing thin.

I love Merino wool, there are no doubts about that. That being said, these are the most bombproof socks out there bar none. What they have in durability they lose a little in cushion. Comfort wise, they feel snug, but no the most breathable. I still love them, but they are not my go to for running or biking, but a great sock to stand all day in at the shop. Again, the most durable sock out there (but lets see what Point 6 has to offer)

Love these socks. I will never buy Smartwool socks again. All of my Smartwools have holes in the bottom of them after about 6 months. These socks are much more durable. I love the feel too. Buy them--you'll love them.

Fantastic socks for long distance hiking. I've used this model on five different 500+ mile hikes and they have been perfect. Much more durable than SmartWool thin socks.

GREAT running socks for hot Florida weather. Dry quick and wick perspiration away from feet. No rub point on toes or heels. Also used for day hikes around Ohio. Socks do not slip or cause blisters due to friction. Worth the $.

Darn Tough makes some of the nicest socks. This is a super thin sock. Hate socks but need them in bike shoes and running shoes and these are the most comfortable and seem to wear great. Very happy with these, buy some and see for yourself.

I normally wear a large but that was too small and the x-large was too big. I bought the XL figuring that it would shrink, but it did not. Really can't wear the socks because the extra material is ill-placed and causes discomfort.
Aside from the sizing, I don't think these are as great as many say they are. I would agree that they are more durable than Smartwool, but not nearly as comfortable.

Favorite socks ever! Yes I am a merino lover and pretty much go head-to-toe in the stuff, but Darn Tough kills it making a great fitting, well made product. I'd suggest any one of their socks.

These are the best darn socks in the world, no kidding. This particular light weight summer sock is fantastic for light hiking and especially bicycling. Darn Tough makes their socks with either CoolMax or Merino wool. It's your choice, but I find wool to be better than CoolMax, because it wicks moisture better and keeps my footsies nice and dry (unless I decide to swim in my socks)! I think CoolMax tends to keep the moisture closer to my skin, but maybe I simply sweat too much. Try both CoolMax and Merino wool versions, then decide for yourself. I made my decision 5 years ago and have never recanted. I love these so much that I sleep in them. Well, maybe that's just a bit of an exaggeration on my part. But just try 'em. Your feet will love you for it.
