New in package. They sent the wrong size. I bought these slippers with microwaveable insoles for my elderly mother who was not very mobile. Very cozy with nonslip soles. Mary Jane slippers are ideal for the elderly, easy to put on, does not put pressure on the feet and are lightweight and breathable! Chronic cold feet, sore feet, arthritic feet, inflamed feet, tired feet - they all deserve some TLC after a long day. From hurting heels to aching arches and tortured toes, treat your tired tootsies! Get warm in no time! Place the Snook-Ease shoe insoles inside their heating bag (included) and heat in the microwave for 60 seconds. Place immediately inside your footwear and enjoy warm & toasty footsies. Use at home, at work, during the day, or for a relaxing night’s sleep. Unlike electric sheets or blankets, hot water bottles, or massagers which require electricity, boiling water, or batteries, Snook-Ease is safe, hygienic, lightweight, discreet, reusable, reheatable, washable, odor-free, and squeak-free. Snook-Ease inserts are engineered with unique minerals that rapidly warm up in 60 seconds, gradually releasing warmth for up to 30 minutes. Feel the heat fading away? Heat Treat and Repeat - No More Cold Feet! Snook Ease technology is based on a mixture of several natural earth minerals that are molded into various shapes. When heated, this mixture quickly absorbs heat and slowly releases it for up to 30 minutes. Made in the USA. From smoke-free home near Jubilee Hospital.
