Body Innovations Heat/Vibration Foot Warmer & Massager. Great Condition, One size fits most. I wore a size 9 and I still had some room so maybe up to a size 10 women’s 8.5 men’s. Small stain on the bottom of the warmer, please refer to the last two photos. I loved sitting on my couch, binge watching t.v. wrapped in my furry blanket and my feet snug in this wonderful invention. Reason for Selling: My husband just purchased me a brand new one with all the bells and whistles, he’s the best! I want you to enjoy this, it can be considered self care also 😊 Treat yourself, you deserve it. Used a handful of times and my feet were always freshly washed prior to use.
