Double Layer Seamless Toe
Wrightsock's Double Layer styles offer a seamless toe like most performance socks do these days; however, as you can see on the below images, Wrightsock's seamless toe looks a bit different. This is due to the required attachments that connect the inner and outer layers together for our Double Layer system.
Even though it looks a bit odd, our seamless toe acts and feels the same on your foot as any other seamless toe design.

Customer Reviews
What our customers say
It’s been 3 weeks since I ordered(#56160) two pairs and package probably was stolen or lost. Tracking stopped 2 weeks ago. I sent an email to wrighsocks and someone named Kimberly replied something like “contact post office in your country”. I guess I’m on my own
Bought the socks from Reddit recommendations. Wore the cool mesh II on a 20k trail run last weekend. Initially I thought they were comfortable, but on the incline I had some hotspots on my heels and on the long descent I got blisters on the bottom of my feet.
I know there are more variables to blisters than just your socks, but I was wrong in trusting the no blister promise. Not a bad sock for maybe shorter days? Or just wearing around, but I’m going to stick with my injinji toe liners with a darn tough over.
I bought some of these socks almost a year ago for hunting in warmer weather. I like them a lot. I walk a little over 9 miles a day for exercise, and have issues with blisters on my feet in the hotter months. I got to thinking about it and ordered a couple more pairs of these socks just for walking in. They have resolved my blistering issues.
No. No, there is not. My 6th pair of Wrightsocks for hiking and I won’t buy anything else.
Great socks. Comfortable and warm. The customer service is outstanding and reliable.
I need to return these as I do not wear plastic. Merino wool was my goal and the materials were not listed in the posting for these socks. I am extremely disappointed and will send them back as soon as I hear from the company what their return process is.

Wrightsock Customer Service
I wear orthotics in my cross country ski boots and for years I put up with blisters that formed on my inner arch from rubbing on the orthotic. I was told about Wrightsock so I tried them and was able to ski 20 miles with no blisters! I can’t believe it.
Love the merino wool tall socks for winter running.
Stay in place.
Warm.

Merino Coolmesh II Crew Anti Blister System
I was hoping to find the darker green color that I have bought in the past but cant seem to get them right online
The best pair of socks I own. Comfortable, feet do not sweat
Never received the gods!!!!!
Had I read the fine print.... I would have known these were made with recycled plastic bottles, There is no way I would have bought them !! Don't want plastic in your socks,on your skin and bits of plastic in you laundry from these... Steer clear !! Into the garage sale box they went !!

Wrightsock Customer Service
I am 70, started hiking long distance trails at 65. Guess I can’t really say these are the best because they are the ONLY socks I have ever used hiking, They are so comfortable, soft, warm, and cool when needed. I have never gotten a blister using them so would never even try another brand. Thank you, Wright socks!
Hi Ann-Marie,
Thank you so much for taking the time to leave such a positive review. We are thrilled to hear that our Merino Coolmesh II has been your go-to choice for hiking for such a long time. We're so glad to have been a part of your hiking journey and we hope to continue providing you with comfortable and blister-free socks.
Happy hiking!
Wrightsock Customer Service
I’ve been wearing Wrightsock socks for years. I still wear two pair from my first order. I hope the current socks are still the same quality. I order XL size and dry the hot to shrink a little for my perfect fit.
They work great for every day wear and for hiking.
I really love these socks. I walked the Camino de Santiago using Wrightsocks and Salomon X-ultra 4 Gore-tex shoes. No blisters on the 300 km trek. The socks lasted longer than the shoes. The Salomon shoes were great but not very durable.
excellent product and service
These are the only socks I wear now.
I bought these after buying a new pair of boots that blistered me up badly. After I healed a little bit I put on these socks in hopes to break in my boots some more and, as stiff as my boots were, I still didn’t get any blistering. So that was a surprise. (May have to buy me some gel pads though.) Also the socks make it easier to slip the boots on and off.
Looks like a good pair of socks but they’re a gift so I can’t say more than that
Socks true to size, good fit, comfortable, shipping on time, no complaints except price so high.
I took 2 pairs on a 5 night, 90-mile backpacking trip. They were comfortable and I got no blisters. Plus, they look good as new.
We just finished an 80 mile hike in the Cotswolds. The lined anti-blister socks were extremely comfortable. No hot spots or blisters!
Great socks!
Nice!!!! Love them.
Lots of hiking in Garmisch Germany. No blisters or hot spots.
Haven't hiked w/socks yet. Have wore them around seems a little tight for me but size range is correct from website. Have to tryout on longer hike on IceAgeTr. Soon.
Socks ate comfortable and of course, no blisters!
I have 8 pairs of your socks now. They’re my favorites.
I have very skinny legs and yet the cuff on these socks is too tight
