Apparently these trainers were 'made' for running. I only bought them, however because I like the colour. As far as foot support and lightness is concerned I'm none the wiser, but they are very comfortable.
I recently had a long hour flight and shoved these on for sheer ease. 8 hours later my feet were in better condition than I had expected, and that was all to do with these bad boys.
They'll set you back $90. Find them in any Nike store, or online.
