I fell in love with the original Cliftons the first time I ran in them.  They were a perfect shoe for me.  I run about 20-25 miles per week.  My biggest challenge is finding a shoe with a toe box that isn't too narrow.  The Clifton 1's were great because you couldn't even feel the upper, just the soft ride below your feet.  Not sure why anyone felt a thicker tongue was a good idea.  Just adds pressure on the top of the foot.  Maybe designing for kick-ball?  Don't know.  I need support below my feet, not pressure on top.  The toe box also digged down onto the top of my toes providing instant blisters the first time I ran in them.  Huuuuuge bummer.  I've returned my Clifton 2's and bought several 1's.  Enough to get me through a couple of years of running, hoping that Hoka releases their original magical design once again before I wear them out.
