These sandals are extremely comfortable - I've been able to go for walks in these without getting blisters.  They're also really nice and I get compliments on them.  However, in the middle of my first time wearing them, the right sandal began making noise when I walked.  Every time my heel hit the ground, an air &#34;woosh&#34; would come out.  I don't see any part that has a gap and I've tried pressing on the heel while trying to feel where air is coming out and I have had no success.  My feet are comfortable in these but I'm not happy at all walking around and hearing &#34;wooshing&#34; noises constantly.
