Shame, as I really wanted to like these. Too bad because the style was nice. See the comparison yourself in the pictures. I was able to walk several miles and not be uncomfortable. Turns the ANC on and off. Vestido ligero para verano o estar en casa. I wore these shoes around the block and developed two, huge blisters! I was going to return the slippers at first because they felt tight even though they were my normal size. You shouldnt use silicone Tubing as it leaks co2. My only wish for these is a magnetic closure for the instep strap.
