I purchased these at a running store, after form analysis, over a handful of other options that were also recommended. For background, I fall more into the casual runner category. Prior to switching to the Cortana 2's, i was running between 15-25 miles per week in minimalist shoes (vibrams and new balance minimus zeros). I started training for my first marathon in January and as the weekly miles ramped up, I developed shin splints. In other words, the miles increased quicker than my feet and legs could adapt in minimalist shoes.

So I headed to the local running specialty store in search of a more forgiving shoe, that hopefully wouldn't impede my form or feel like boats strapped to my feet. I am a midfoot striker, and not comfortable in bulky and heavy running shoes with a huge heel and (heel to toe) drop. I also over-pronate a bit (landing slightly on the outside of my foot), but since I strike more mid to fore foot, I didn't think I needed a heavy stabilization shoe. After testing a number of shoes on the treadmill, most with minimal to no drop, some neutral, and some with slight correction to over pronation, my 2 favorites were clear. I liked these Cortana 2's and the Brooks Pure Flow 2s the best. It was really a toss-up since both felt comfortable, had a nice cushion to the forefoot, and were fairly light for this type of shoe. I chose the Cortana 2's because they last longer, aka for more miles before needing to replace them. On the flip side, they cost more, but I still opted to give them a try.

I got home, went for a run, and loved them instantly. I still had shin splint pain in my right leg, left over from the minimalist attire, but over a few days it actually improved, despite continuing to run, using the Cortana 2's! The shin splints have not returned. Running in these shoes is great, and I can't see myself switching back to the vibrams anytime soon. They fit my foot well, have great cushioning to absorb impact, decent spring, and the mesh top is breathable, light, and just fitting enough while still allowing movement in the toe box.

Fast forward 2.5 months and 300 miles later, and I still couldn't be happier! I actually just came on Amazon to check their price here because I'll be in the market for my second pair in another month or two. I saw it only had one review, an unfairly negative one at that, and decided to share my experience. In summary, I think they are a great shoe, particularly if you are looking for something with not much drop (only 4mm), but good cushion, fairly lightweight, and a slight post for mild over-pronators. That was me, and I'm happy as a clam!
