Great Pair of Socks

These socks are great! They make my boots even more comfortable than before, keep my feet warm, but at the same time keep them dry. And for what it's worth, they even look good too.
Another great Carhartt product.

Irregular socks

I was about to order the socks and was told that they had the irregulars at a much lower price....the girl taking the order said that they were the same sock only that the knit in label might be off just a bit and I said no one will see them so it doesn't matter. I was very happy that she had suggested the irregular socks....good price to...and the same quality.

I purchased these socks for my son to wear to work on cold winter days. They are so soft and comfortable he wears them instead of slippers during his evenings at home. I'm considering buying more for him and some for myself.

Thick, cushy and warm.

These feel great immediately. They are much thicker than standard socks so keep that in mind for fit (your boots/shoes may become tight). If you sized up a bit or you already had space, they will be perfect, and the cushy feel and warmth are worth it. I can't speak to durability yet, but the comfort is amazing.

Really Irregular?
October 5, 2011

From: PA Age: 35-44 Gender: Female
I bought 4 pairs of the A66 socks over 4 years ago. I find they pad my feet better while wearing sneakers and standing all day. I finally decided to order some new socks(without holes), and went with the factory 2nds/irregulars. I ordered a bunch of pairs and honestly I don't see anything wrong with any of them. The socks come nicely packaged in normal retail packaging, and are the same high quality and the non-irregular sock. I wear a size 15 shoe, and I find the XL sock size the best out there for big feet. I have NOT been able to find a thick , heavy sock anywhere , and in big sock size. So stock up! Thanks Dungarees!
