Not a good product at all. keeps my makeup off the counter and looking nice. If you have a cold environment you walk around in a lot, you should pick these up or the crocs lined. 1) Turn the volume down all the way. he finds them more comfortable than any pair he owns. But I am a music lover, and I have been enjoying these my music on these speakers. Still working very well. My feet are much warmer in these than my former leather kitchen shoes. After five hours I got the “high” charge. I own several Crocs same size.
