The microfiber material quickly absorbs water from wet shoes, assisting in drying. I've even had my kids wear them as room slippers and "mop" the floor while they played, haha! I bought several, and since I have some unused ones, I'm putting them up for sale. The original packaging isn't in the best condition, so I've marked them as "Like New." I may repackage them in a different bag for shipping. Thank you for looking.
