Not sure if they will keep feet warm during winter in the house. Auto shut-off feature is nice. It also holds my familys bikes with various tube shapes, angles and diameters just fine. These are hands-down the best cotton swabs that I have ever used. These feel pretty narrow when I first put them on. Also, directions weren?t clear that one bar is longer than the other. The athletic soul is very supportive, which is one of the main reasons I wear them. I am yet to receive the refund. These beads added a lot of color to my nieces stretchy bracelets for Christmas! The sound quality is great, noise cancellation fine and they last all day on one charge.
