Q: These things are great. I purchased them because I tend to get a blister between two of my toes when I walk a lot. They are comfortable and easy to put on and take off. You can wash them and they do not stretch. I would definitely purchase them again and would recommend them to anyone who has toe issues.

A:
positive
