Review: Great Socks! - Great socks!
Review: I love all my Injinji socks! - Started wearing Injinji toe socks about 4 years ago and haven't worn a traditional pair since. Living in rubber boots in a remote fishing village in Alaska, I have suffered through endless athlete's foot my whole life... Until my life was changed by Injinji. Haven't had it since! No chemical solution due to having absorbent fabric between the toes. The feel took a couple days to get used to and the shortcut to getting them on took a few more days to master, but I just love these. I mostly wear the no-show length, but ordered these for my boot days. Taller socks takes a little more time and effort to get them on, but not that tough. I have a customer who has to take a picture of my feet every time he comes through to show his office staff in his town what my feet look like today... If asked, I usually respond that I may look like a dork, but I love the feel and comfort, then go into the foot-rot sales pitch. I don't think I have made any conversions to the Injinji cult, but I'm definitely a life-time member...

## Questions & Answers

**Q: What are the functional differences between this and the midweight Xtra life crew? I see there is less coolmax and more nylon? More durable?**
A: I feel like these have a bit of compression on the arch and mid area on the sole of my foot. They are thicker than the basic mid weight, too.

**Q: Is these cotton ?**
A: It must be a mix of cotton and polyester (spandex or some other material like it), it does not show.

**Q: How do these compare to the 'Trail Midweight' version- are they thicker or thinner? (please don't respond unless you own both)**
A: It helps when I use it to run outside during the winter in Colorado. So, thicker I suppose.

**Q: I wear a 9.5 in woman's shoe, what size should I order? small or medium? I have skinny/boney feet.**
A: I wear 6 or 6.5 and small in socks. Try a medium.

### ⭐⭐⭐⭐⭐ 2400 miles on 2 pairs! INSANITY!!!!
*by D***N on February 11, 2020*

EDIT: These are even better than I hoped!! After successfully thru-hiking the entire Pacific Crest Trail (2653mi) in one summer, I've got a few praises to sing, a few caveats to note, and I sure hope the manufacturer is listening. Firstly, I'm dead serious that I started at the US/Mexico Border and hiked through the mountains of California, Oregon, and half of Washington before these finally gave out. I had 2 pairs, which I switched out daily and rinsed in a creek when possible. For reference, I went through 5 pairs of trail runners and all of them had the fabric worn out in the heel, but these socks never wore through in that spot at all. Not just for me either, my girlfriend wore the same socks with the same experience. Other hikers who wore the famous Darn Tough socks? They replaced theirs at a maximum of 800mi per 2 pairs. Sometimes 400mi. These are the new gold standard, if you ask me. Important to note, the other Injinji sock models all fall apart extremely quickly. They are well known in the thru-hiking community to be very short-lived. Cherry on top: I never got a blister and my girlfriend only got a couple minor ones, despite usually getting massive blisters that would've ended our hike in the first week, if not for these socks and one other crucial component - Badger Foot Balm. Seriously, use it. Apply it sparingly every morning that you run/hike/backpack and you'll see far less blisters and/or foot rot. Other hikers started seeing blisters again in Washington when the weather got wet. We were fine. How? Here's my theory: It's most likely the composition being largely nylon, with a heavy dose of Lycra. Most other Injinji socks contain some amount of wool and polyester. Wool has it's place; this isn't one of them. Wool is popular because it's supposedly less smelly, but you sacrifice durability and wool holds WAY more water than synthetic. That means they stay wet longer, which means your skin gets soggier, weaker, the layers separate creating a blister. In a non-waterproof trail running shoe, a hiker or runner will frequently just cross a stream and walk their shoes dry. Synthetic allows the sock and shoe to dry in a fraction of the time. Plus, nylon is just more durable, period. That's what you want on a thru-hike or ultra-marathon, where you can't easily replace the sock 50miles from town. The downside of nylon is that it's abrasive and can cause serious blisters. That's what the extra Lycra is for. At the end of every day, you could see the fabric imprint clearly on my skin. The sock doesn't go anywhere on your foot, when properly sized. I wore a Med sock and a 10.5-11.5 shoe. These socks have a bigger compression zone around the arch and another around the heel. It works exactly as designed. The caveat? I ordered 2 pairs in black to begin with. The replacement socks were colored. The colored ones have already shown more wear and don't feel as tight. I'm no material science engineer, but I have noticed that black plastics are more durable than clear ones. Not sure why. The takeaway is simply this: Order the black ones in a tight size, use Badger Foot Balm, and you'll be the happiest hiker/runner on the trail. ------------------------ My toes stay dryer in these vs. regular socks, which results in less blisters. I have finger toes and they still get right down in between. The compression is nice, not so much for support, but because it holds them on my feet better. When there's movement in my shoe that might cause a blister, it happens between the sock and the shoe, not my skin. Haven't felt a hot spot yet. They dry pretty fast too. I stayed away from wool blends for that reason; been down that road and I'm sick of the matted, soggy feel of wool. These should be easier to clean daily on my upcoming thru-hike. I'll certainly update this review if I have a problem with them.
