Asics keeps changing the shoe design - not liking this generation...  Dated sole design with less detail - the tech may be great but the detailing is absent.  So far the sport-lines over toe can be felt while running even short miles.  As the runs get longer ~ anything from 10 to 20+ ~ if you can feel an impact area, count on loosing skin...  Aesthetically, poor color options - weak blue and green...?  OK - a few weeks of miles in these now...  PLEASE restore to prior design direction, this is not a good generation at all.  Would not recommend.
