These slippers resemble a slip-on loafer, but offer a pull over wide Velcro strap so you can make a quick, customized adjustment based on the condition of your feet without looking like a medical shoe. These sandals are gorgeous and very much on trend! It doesnt pay to go cheap, think about how much your phone is worth. The only thing I did notice was the right shoe didn?t light up very easy compared to the left shoe but it did light up sometimes. If you feel that four years out of a pair of slippers is fine, then consider buying a pair. It is made very well. Saved myself $150 repair fee by buying all the parts myself on Amazon. (and I have one not too far away)I like the extra color at the top of this shoe and unlike many Duet models, I like that the color on the bottom is darker than on top. Got this for my husband that travels a lot and looses headphones a lot. Sewn in flap ripped off easily when removing.
