When I walk the squeak and make fart noises I’m so annoyed like that SpongeBob episode with the sneaky boots. Great product and great service from the seller! I didn’t charge them when they arrived, even after listening music (over 3 hours) it was still going. They are louder now. Pay a little more and buy another brand and do your hard earned dollars a huge favor. The were much nicer in person. THEY ARE SHARP, so be careful. Delivered within 2 days, great job! The grey color looks really nice, almost like a reflective affect, it looks like the photo! If I try to walk barefoot, with socks on, or with other types of slippers, my feet hurt terribly and I feel as if I will fall.
