Short initial review, I will update my review after wearing it for a period of time! So I can wear them comfortably feet swollen or not. The caller on the other end of the line is the one that was hearing the popping, so I would say there is some small issue with the microphone. Its surprisingly hard to find a comprehensive book on Reconstruction - especially compared to the multitude of books on the Civil War itself. This device has too many disfunctional quirks to even list. Anything Mackie sells is high-quality. It?s not a big deal though. Overwhelmingly negative feelings on this one. Note that they are very breathable and not at all waterproof! But the shoes leather gives color on my feet.
