Too comfy and adorable 🤩
These socks are super soft and comfy, so cozy. These are the best feel good socks. The material is medium thick, so soft and fluffy. You may find a couple of fluff pieces here and there in your bed or floor after a while. They're still great socks to enjoy and lounge around in. I would suggest turning them inside out when you wash them. A good price for them too.

Soft fluffy socks for a comfortable sleep
Style: 1 Pair, Color: Men's Heather Charcoal, Style: 1 Pair, Color: Men's Heather Charcoal
I am a woman with size 8.5 or 9 feet. I purchased the heather (salt and pepper) pair of these for men, because I was tired of socks that squeezed my toes together. So these have a few inches of extra space at the toes, which is more comfortable for me, since I got these to sleep in. I am including a photo of these next to my usual too tight socks for comparison. When I took off my usual highly elastic tight socks and put these on I literally breathed a sigh of relief. These will keep my feet warm without being constrained. These are neither thick nor thin, but fluffy and very soft. I suggest that anyone who gets these is careful about taking off the small plastic piece that attaches the two socks together. Don't just yank the two socks apart, use some scissors to carefully remove that little piece. Also I suggest hand washing these. Recommended for those of us ladies who are tired of socks that squeeze their toes, for sleeping, and around the house.

Ultra Comfy Socks
Style: 1 Pair, Color: Pink, Style: 1 Pair, Color: Pink
These socks are incredibly soft and comfortable. They have a wide band of elastic incorporated into the top that isn’t binding, but holds them up and keeps them from slipping. I purchased one pair and liked them so much, I purchased three more.
