These were $899 when I bought them brand new a year ago, they appear to be on sale for $799 now. They come with a two year warranty, so there's about 11 months left on that. However the boots are basically brand new -- I used them maybe two or three times fully clothed before my chronic health issue cleared right up (!) and they have been collecting dust ever since. (I am not crediting the boots with my recovery 🤣 although they definitely worked as promised!!) I don't have the original box, but I have the charger and everything it came with. I just tested them and they work. They're great boots, someone should snap them up at a bargain price! Please note that this set weighs 10 pounds, which means I pay a $22 shipping surcharge. Size M
