text: Turns out the &#34;Authentic Original&#34;  shoe when noted as an &#34;Echo&#34; is neither authentic nor original.  This is a different cut of shoe entirely.  Lower on the foot, less secure on the heel, and at risk of cutting into the top of your foot at the arch.  Look VERY carefully at the picture and compare to the regular AO shoe and you'll see the differences.  Very slight in the picture, totally different shoe on the foot.
