First off, I wear headphones 12-18 hours a day, 7 days a week. I cannot explain how amazing these shoes are! I have textured walls but still gave it a try and very happy I did. There is a little bit of noise that you can hear outside the headphone however people nearby you really will not notice it. I wanted a shoe that would add a bit of style to simple outfits. 5 UK but the 5 is better for me in these. Wires have metal connectors, which is great. I love Birkies and have long wanted a pair of Shearling sandals, but have held off, mostly due to the price. Everything else is just right about them, but they may as well be open back slippers since they wont hold your heel. They do run a little big because they are good leather and they stretch.
