Comments: 5'8" 165 pounds, neutral pronater. Was looking for a daily high mileage weekly trainer after Mizuno discontinued the Precision, this is it. I run in Saucony Kinvara's for track + 5Ks, but the Kinvara's aren't comfortable for distances beyond 5-6 miles. The Cortana's are light + fast like the Kinvara's, but with more cushioning. Great shoe.

Comments: I purchased these about 3 weeks ago from Running Warehouse (the most awesome place on Earth for running shoes, apparel & accessories) & I've got close to 60mi on them. Got them in on a Wednesday & my first run with them was the next day - I went 10k...wow! Comfortable & fast. During this training run, this "46 year old, 175lb'er" clocked a 50:36 - a PR for my 10k. That Saturday (only my 2nd run in them), I ran a half-marathon road race - turned in a PR (1:54:28). And what was just as exciting for me along with shaving close to 3 minutes off my HM PR was how my legs felt at mile 11 & 12...they were feeling great, even running into 25mph head winds the last 2 miles! I have to say that these Cortana 3's kept me feeling well throughout. First putting them on, I thought the upper & toe box were going to be too snug...but I've run in Kinvara 4's before & they had (on me) a similar feel. I didn't even notice any snugness on the run. I'm a neutral runner & I was hesitant about the medial black rubber "post" (but it's not a post, I guess). But for me, it's probably assisting me on the further miles. It doesn't bother me at all. The price is...well...pricey...but again, for me - a guy who's pretty picky on his running shoes & have tried a lot of them - I'm so glad I spent the extra. I'm not disappointed & while I have the Cortana 3's (oddly enough for me) I'll be road running in just these. Love the brand - love the shoe - love Running Warehouse!!!

Comments: I just ran in the Cortana 3 last weekend at Ironman Lake Tahoe. I had the fastest run split of the day with a 2:52 marathon. I decided to wear the Cortana instead of a pure racing flat and was not disappointed. Any time lost due to extra weight was made up for in the later miles when my legs felt fresher and I was able to push the downhills more. I ran a 16:40 5k during a downhill section between 19 and 22. Very happy with these shoes. Uppers felt a little bit tight, but not restrictive. Forefoot definitely isn't wide, it is snug. But flexfilm definitely allowed for comfort.
