I had ordered these before in black and grey and they were great, fit perfect. But these run small. I had noticed another reviewer said the same but thought I'd risk since they were cute. I'm not sure what color has to do with it, but tight at ankle and at 'toe'-less part. They are now in my donate bin. Waste of money, will not purchase this brand again. Great idea, inconsistent quality.

I use these when I go get a pedicure in the cold weather. They work perfect.

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.

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.
