Alright ladies and gents, anyone wear the Nike Lunar Vengeance or Adidas adios and have an opinion on them? I'm looking for a good marathon flat and found these two to be maybe what I'm looking for. Or is there another flat you are just in love with and would recommend??? It's gotta be kind of light (not over 9 oz; preferably not over 8 at least) but have some cushioning. So not like the Nike Katanas for example... I've worn the Nike Lunar racer but they made my feet hurt doing mile repeats on the track (but maybe that's because of all the turning...)
