I had the Pegasus Premium's in black for six days and wore them 4-5 times to work when the right Zoom Air unit failed. I work in an office so most of my day is spent walking on carpet, vinyl, and concrete surfaces. However, I usually take a mid-afternoon, outdoor walk, to stretch and get fresh air. The walk has mix of services from concrete, grass, and gravel. Again, normal surfaces that anyone should expect to encounter on a walk or run. While on the short gravel path, I noticed that the right shoe suddenly felt "flat." After getting back on the concrete I could hear air escaping from the right shoe. Once I returned to my office, I inspected the shoe and noticed a small tear in the forefoot area of the Zoom Air Unit. So I am guessing whatever happened, happened on the gravel path. So I would caution anyone from purchasing these shoes as the Zoom Air unit seems to be EXTREMELY fragile. If there is a possibility that you may be on any surface, other than one that is perfectly smooth these shoes have a good chance of failure and you will be out of luck. I know Nike's warranty doesn't cover "wear" but this seems to be an extreme case of fragile material failing for doing exactly what it was meant to do.

love it, love it Nike, more colours please

Très beau design mais une semelle trop molle au niveau du talon.
