Can’t beat this for the price. The headphone jack didnt work. I bought a pair of wireless headphones from Beats by Dr Dre four years ago. What I noticed during that time is that these will periodically have a promotional discount available. With each step the heel slid off even though the top portion was adjusted to be snug. I would recommend a half size up like someone else mentioned. After reading all the other reviews on this brand of slipper, I was nervous about them being too small as so many other customers complained about. But, at this price, it really doesnt matter so I just buy a new pair. These Casmags are a really good deal at just $30. I sized down to an 8 because I used to be an 8-8.
