I have a medium to narrow foot, narrow heel, bunions and needing larger toe box.  These were comfortable right from the start and sort of felt like an Earth Shoe with lots of cushion added.  The heel goes down a bit and toes seem higher which could be a problem for my bunion pain in time.  I need my heel to sit higher than my toes.  My orthotics fit in these but snug and need a thin sock.  I have average to flat arch.  I am not sure about jogging in these everyday as I think I risk tripping from the height of them. My toes hurt this am from a jog yesterday.  They do have a good cushion and feel very different from Asics which I have worn many of for years.  We'll have to see how these perform over time.  After getting these on my feet my Asics feel very inadequate.  They get 3 stars because of the tripping factor but 4 stars overall because they are so comfortable right out of the box.  I don't anticipate blisters as others mentioned.  I take an 8-8.5, an 8.5 in Asics.  These are an 8.5 and fit perfectly.  I will have to wear my orthotics in these to raise the heel and put less stress on the toes but with those they are close to perfect.  Time will tell
