With my first half marathon pending, and a knee pain that stopped me in my tracks after a mile or two, I took my shoe choice very seriously.
I tired on about 30 shoes among two running stores, Dicks, and Modell's. I had an employee at the local running store look at me walk and run - he told me that he thought I had a neutral gait, and therefore did not need stability shoes. The only shoe I liked was the Nike Zoom Vomero 10, even though I am not really a fan of Nike shoes. I had to run and ended up visiting a second running store where I purchased the Saucony Men's Ride 8 after trying on about 12 shoes. This shoe felt pretty good, but I didn't like the look, felt that it was bulky, and it just didn't seem like a truly high quality running shoe to me. For these reasons I ended up returning these shoes. After trying on another 15 shoes at 2 stores I decided to purchase the acclaimed Adidas Ultra Boost, even though I am not really a fan of Adidas either.
I tried running with the Ultra Boost on several occasions, but would get excruciating pain on the outsides of my knee, radiating toward to medial knee, after running only a mile or two. It began to occur to me that too much cushioning might actually be a bad thing. After a ton of research and careful examination I determined that I was experiencing iliotibial (IT) band syndrome. I could also see that when I ran my knee was fluctuating all over the place, therefore irritating my IT. What I discovered is that I actually have flat feet, and this is a huge problem when it comes to knee alignment. You need support to keep the knee in alignment and prevent shifting of the patella. Back I went to the running store where they were kind enough to make a second exchange for the On Cloudflyer, which I had also done some research on as this was the most comfortable shoe besides the Ultra Boost. This shoe has stability features while also being very well cushioned.
Long story short, this shoe is AMAZING. It is well cushioned and has amazing stability while letting your foot track through it's natural course of motion. The forward propulsion and heel to toe transition make this shoe seem very fast. The shoe does fit wide, so I'm not sure how it would feel if you have a narrow foot. To me this feels great, but it does not fit as snug as the slipper like feel of the Ultra Boost. I just completed that half marathon, and this shoe in combination with KT tape kept me feeling great throughout the race. My feet felt a bit sore after, but that is to be expected. The next day I also felt fantastic, despite my longest run being about 6 miles prior to that. If you can try these shoes I recommend it, and it you cannot just buy them and return if you need to. I typically wear 11 or 11.5; in these shoes I had to go with an 11.5 to avoid rubbing my toe at the end. The laces are odd, and don't do a great job of tightening the toe box. This works well however, since tightening the toe box actually make the insole rub my foot. Keep it wide and these shoes are extremely comfortable, not to mention looking awesome.
