Good thing I looked at my old pair. And 5 G is coming - heaven help us. I was so impressed with these shoes that this is actually my first time i have ever taken the time to write a review for a pair of shoes. I was able to use the variety of hooks for air tools, circular saws, power planers, sanding belts, etc. They are soft and extremely warm - too warm on a moderate Southern California day like today (70 degrees). Im using them in my vacation rentals and they go with both the farmhouse and rustic decores. Another thing I love about these sandals is the price. Same goes for microphones. Save some money it will work if its a gift or for yourself. Once installed, playing the speakers via a Bluetooth connection is a breeze.
