It did help with some sound proofing as well. com they are about $400 USD, and I think that is a great pricepoint for these. It is a real hassle. So low that I couldnt hit checkout fast enough. Product is exactly as expected - and delivered on time. I?m in the process of buying more Vioncs shoes. Bought these slippers on 3-Sept-2019, and the heel on the right one is wearing out! Why? Because Ive had other cheap hooks bend and break on me and these are not going to do either any time soon. They were in a plain cardboard box. Its only a minor annoyance however.
