I have owned this shoe for two weeks now and plan on taking them back.  I was excited about this shoe because of all of the reviews.  The problem with the zigsonic is they did not create a way for the laces to hold the tongue in place.  I have to lace the shoe down to the point of cutting off blood to my foot for it to even try and stay in place.  However, after a few hours is laying over to the side.  If I lace them so it's even remotely comfortable it's down to the side in just about half an hour of walking around.  I looked around all over the web to see if I was just lacing them up wrong but did not find anything.  These shoes also hurt my feet so bad just walking around it's ridiculous.  Maybe these things were just built for hard core running and that's it.  Not intended as a daily shoe to just wear.  They do look awesome.
