Wasn't the colour or size I ordered or received therefore I can only comment that I can't comment on it the above. But the pattern was in a lime green colour and in small size are awesome look great, very comfortable, fit well and best of all get a lot of attention as I wear them with slip on shoes (croc's of course). So far some lovely smiles from two charming middle aged ladies so far so for a 65 years old male with blue eyes reasonable amount of hair left ... that's not too bad and the green socks go with my blue eyes and shoes so they really do all match. That combination and for someone who always drinks McDonalds coffee and can still afford a newspaper they know I must be someone special to be able to wear socks like these. Well at least they keep my feet nice ... MoreWasn't the colour or size I ordered or received therefore I can only comment that I can't comment on it the above.

I love these socks. I've seen ultra runners use these and they swear by them so I fogured I would give them a try. Easy to say I am super impressed and will continue to wear / buy these socks again in the future. If you are on the fence, give them a try.

I used to have issues with blisters between my toes. The injinji line was a game changer for me. These socks in particular, the Ultra Run Crew CoolMax Sock, are my absolute favorites for their comfort, cushion, and their durability.The awesome functionality of Injinji will quickly help you get past the odd look of toe socks and the extra 10 seconds it takes to put the sock on. No more inner toe blisters + comfortable toe splay for the win!

I love them. I won’t run in any other sock. when I’m taking on long ultra marathons these socks are fantastic. No blisters, no hot spots, no foot issues at all.
After trying many different socks to overcome toe blisters and arch blisters I found that toe socks were the way forward. After using Injinji for the first time I knew I was on to a winner. After using a different product from their range I found that they were a bit too thin. I then went on to try the ultra model, and what a difference! These socks are amazing and I remain blister free after over 30 miles! The extra length in the crew sock prevents any rubbing from shoe tongues. I now own 2 pairs of these and won't run long miles in any other sock!
I bought them for a friend who claims he has "fat toes". Basically whenever he runs more or plays football, his toes rub against each other and the skins break open. It's not athletes foot. So I got him a pair of those and teh problem has stopped. It took him around 30min to get used to them, but now he loves them.They give a nice support and keep the feet dryish he says.
People get weirded out by toe socks, say they're freaky and hard to put on.Try it, like it, never go back.Countless runs, from Parkrun to 117mile ultramarathons, NEVER have I had a blister. My toes are always happy, after crossing Dartmoor and Exmoor in the rain and snow they weren't pretty, but they were still intact and blister-free!Thicker ones for winter/ultras, thin ones for summer/shorter runs.These are truly ace
Great socks, helped stop blisters on toes. Bit on the thick side, not idea for summer runs. Rapid delivery and great service as always!
I'll start with the negative - the sock is too short. Not full length to the knee, but too long for a simple crew size. Ends up sliding down a little.The toes were very comfortable! I imagined the extra fabric between the toes would be noticeable. But no! It just provided extra comfort and protection from blisters!I do both road and trail running and I tried these with 3 different pairs of shoes, and in all cases they were great.I will definitely buy more of these (though I will try different lengths)
Have always loved toe sock concept, makes sense to separate toes for comfort. I will probably order again soon! Very fast delivery...love the sock geek fridge magnet!
