text: Rest in peace free run. First off I would like to say I LOVED the 4.0's but when I made the switch to the 5.0 I was severely disappointed. Nike made a great shoe into the worst shoe ever. This shoe is not comfortable by any means of the imagination. The first thing you'll notice is the shoes run about a half size small. The tongue of this shoe is horrible, it slips down too far and all 3 edges need to be aligned for it to feel natural. I am only giving this a 2 star review because the 5.0's can take a beating unlike the 4.0's. I will be switching back to the 4.0's soon. Nike ruined one of the best selling shoes they had.
