No long term report yet, but my other Keens have outlasted previous sketchers work and wolverine work shoes by more than two times, so I have high hopes. Great unit! 1 sound) used to be two or three hundred dollars for the nice stuff. Skechers work for me most of the time and these are no exception. I’m just about to order an extra set. The cabels were worn the sound kept coming and going one speaker wouldnt even work. Would recommend cheap and work good 👍 Un regalo a mi nieto y le gustó mucho! The other one i have i bought to hold my husbands ever growing sneaker collection. My mom was gifted a pair and she bragged and bragged how comfortable these slippers were.
