Overkill maybe. They replace a similar product made by gold, Which lasted less than 2 months before sole/heel wore through. I am so glad that I ordered these. Theres still some muddiness, but seems to be slowly getting better. It?s perfect for what I need. The volume will increase or decrease without manipulating the volume control. Dont get me wrong, had it not been for paying for private university for my kids, I wouldve taken them in every color! I have sore feet and I can walk round town in these no problem! Rental apartments never seem to have more than one towel rack installed in the master bathroom. Also keeps my feet clean since our dog sheds everywhere.
