made well
Size: 8-10, Color: Black 4 Pairs
These socks fit really well. Comfortable and the price is a breath of fresh air with other brands of toe socks getting crazy expensive. Just went for my evening run and they felt GREAT.

Comfy and Warm
Size: Women 6.5-7.5, Color: Raisin
I'm very happy with these Original Slipper Socks. I normally wear a 6 1/2, so got these in XS/6 1/2-7 1/2. They are a little long on my feet, but they'll do. I'd rather have them be a little long than a little short, and perfectly sized slippers seem almost impossible to find these days. These slipper socks have a nice, comfy wide toe box, and the cushioned sole is soft, warm, and comfy. The suede on the bottom of the sole make these quiet and very comfy to wear around the house. The wool sock uppers are not itchy, but as comfy as a pair of warm socks.

Perfect for cool weather ...
Size: 12.5-13.5 Women/10.5-11.5 Men, Color: Light Grey Ragg Wool
I see a lot of complaints about fit and outdoor use of these ... I mean, these are slipper socks for indoor use! These are not shoes! If you want to walk outside in the snow, put on shoes or boots and then go outside ...
I have two pair of these and they are great! I really like the real leather soles and foam insole, instead of the cheap plastic soles that are sold on most house shoes ... They were a little tight on my ankles when new, but they relaxed a bit and fit perfectly now.
These are perfect for letting the TV watch you, sauntering, meandering, posing, consuming hot beverages, midnight strolls through the house, napping and all sorts of other indoor inactivity ...
It has been a few years, and I must say, my Acorn's are still working strong. It is about 60 degrees inside, and I'm working in the garage on a cold concrete slab. The red stripes look especially special with my Adidas sweat pants.

Cozy but...
Size: Medium, Color: Light Grey Cotton Twist, Size: Medium, Color: Light Grey Cotton Twist
These slipper socks are nice but could be nicer. The sock portion does Not have a heel; they are tube socks with a footpad sewn on. This means there is a little tightness getting your foot past the turn and then you end up with a roll of sock over your upper foot. Once that is all made comfortable, you are good to go.
I wear mine indoors and out for short trips to the patio and backyard. The sole material looks to be durable enough to last more than one season with this type of use. The footbed itself has just the right amount of padding: not so much that the foot can slid to the side and not so thin you can feel the joints in a tile floor ;-)

Size down. Thin soles are cold.
Size: Small, Color: Light Grey Ragg Wool
The ragg wool is warm and they seem well made.
The foot sizing is very long. I'm a 7.5 to 8 always. The choice was 6-7 or 8-9. The 8-9 is more than 2 inches too long. I'm afraid they will cause a fall. Also know that the cushioning is not as pictured. It is only half the depth of the leather sides. When you stand on anything but carpets, you feel the cold floor. This is all due to the gravity on earth.
