I normally wear size 10. I wouldn?t rely on the lil screws that hold it together and expect to carry a load. Product arrived in different colour to picture shown and in bad condition. With that said when using two speakers in my outdoor patio on the floor of my patio deck in front of my movie screen, the sound was quite audible overall with no noticeable distortion. I wear size 10 women sneakers and I bought size 10 in this slippers and it fits perfectly. This trash is going to be returned asap. I kept mine, though. I live about 20 yards from a highway and noticed a huge different between these and my Turtle Beach?s as far as hearing the traffic in the background. I have chronic migraines and this dry shampoo has the same issue others have: it adds texture. Plastic is what disposable products are made from.
