LOVE these Nike Flex shoes!  Super comfortable!!  Everyday shoes for me!  This style as I read in other reviews seems to run just a tad slimmer than other Nike styles....but for me that is no problem.  I can still put my thicker socks on with them...just loosened the laces a bit.  LOVE the colors and the comfort and I'm sure these will be quality shoes like all my other Nike's.  I bought these because I LOVED the purple and grey color combo.
