Shaun.... better late than never my friend!
I have to tell you this. I have a couple footwear desinger friends that work at "N" over in Portland. While "N" developed that air pillow heel, it has been nothing but a problem for them. They end up replacing tons of shoes where the pillow gets a leak and the shoe is trashed. The guy I play golf with there has gone through 3 pairs in that last year.
So you will now come to see the light and get your feet connected to the rest of your game! Let's see, you have a SC putter, new FJ hat, FJ bag tag..... You are the man!
