I happened to see the soles on these when i was out shopping and figured that these would be an upgrade to his old slippers - Well he loves them! I did and they were too small! That is important, since I am wearing it for 8 hours or more, comfort is of course very important. love wearing it. My first impression was a little disappointing. I can place my Airpods on the charger, without looking, and they are in the perfect location every time Love them as much as my first pair! Lower sound is just. Another complaint I read was that one of the plastic clips broke. Great price for the product.
