But here are the verdict:They do have some sound isolation to a certain extent. Screw holes misaligned. For the money I paid for these shoes, I expected them to hold up for a lot longer than they did. I have worn the ballet flat slippers in this brand for years in my normal shoe size which had always fit perfectly. They were as described and fit fairly well. Did I mention that the silicone band gave me a nasty rash on my wrist because of how tight I have to wear it? I usually use metal bands on my watches because they can let air in through the segmented parts of their links and I wear them loosely. As soon as I put them on, it felt as though a billiard ball had been used for arch support. The volume level control is also a nice adder. It worked perfectly on our E-Z Up Dome instant Shelter Canopy 10x10. As you can see from other reviewers photos, if you have shorter toes, they might be too long in the front and too short in the back.
