My 21 year old asked me to be her partner in the upcoming Disney Princess Half Marathon ... I have always been physically active, but knew that I had to step up my routine in order to be able to compete.  A long time ASICS fan, I treated myself to the Gel-Kinsei after reading the reviews.  From the very first time I laced them, I was able to run for miles - no rubbing, or irritation - no need to "break them in".  Definitely worth the money, and the fact that they are different colors sparks conversation wherever I go.  Please note that if you are looking for the new type of lightweight running shoe - these are definitely not for you.

I LOVED my Kinsei 4's, but could not wear the 5's.  I switched to the Mizuno Wave Prophecy 2's and was very happy, until once again, the shoe manufacturer changed the design for the next model.  I just discovered the ON Running Cloudsurfer in a specialty store.  Despite the fact that it is a lightweight shoe, it felt great and I was able to run eight miles right out of the box.  The shoes felt like a lighter version of the Kinsei 4's, and I am thrilled to run "on a cloud" again. Even better- there was no achiness in my legs after the run.  Hopefully, ON will not change the model and I can finally stick with one shoe!
