My first pair lasted for years, truly a remarkable slipper for $40. No instructions re how to operate the buttons2. I don’t like that you have to plug in USB for the lights to work. Super cute and my daughter loves them, but the entire bottom detached from the slipper and they were barely worn. The manufacturer missed a trick here, I think. , in the cold. It is also available in gray. Would be great to add to a motorcycle or a ATV. Overall I think this shoe will perform well but not quite sure how long it will last. I will say they are strictly for indoors.
