They were so much more comfortable than my old ones! Have to return and order a 10c. Only had them for one week but so far satisfied with purchase, the company has reached out a couple of times just to see how everything is and keeping open line of communication which is a plus! My feet swollen up a tad here and there an I find these so work when I go threw that at time. I sent an email to the company to find out how to purchase more grip strips and no one has gotten back to me. I never complain about anything and this is not a complaint. The oven mitts are unsafe to use! These slippers seem to be well made and are comfy. The only headphones that ever floored me have been the magnificent and accurate Etymotic ER4ps. So in all there?s nothing wrong with the product , it?s just the tape that?s a problem .
