Query: Great comfort!

I bought these mules for my mother who took an international trip. I have had a pair in black and they are extremely comfortable. My mother came for a visit and forgot her slippers. She ended up going home with my mules, she loved their comfort. She liked them so much, I ordered this pair for her international trip. Her feet swell when sitting for long periods of time and she was travelling to eastern europe. She wore then every where she went. They are that nice to wear out sightseeing and great for airport security, when these days you have to take almost everything off.
