Solid colors fit, patterned ones too small
As others have said, the blue socks with flower pattern were much smaller than the solid blue pairs- so small I couldn’t even get it on my foot (shoe size 8). The solid blue pairs I like and still wear, but it’s a bummer to only have 2 out of 3 fit when they cost this much.

Perfect for my needs
Size matches my feet. Good enough quality. Comfortable.

Comfortable toeless socks
Very soft and comfortable. However, the elastic is too tight. Should be wider so circulation is not cut and you are able to wear it at night. Therefore, is not good for diabetic and heavier people. Larger sizes should be available.

Terrible Quality, fell apart
Very poor quality. Came apart after one washing. Unraveled. Would not purchase again. Wish I had not purchases the first time.

Socks
They fit okay and they're comfortable but the only problem I've been seeing is that they're starting to unravel at the toe end
