More i wear them, the more i like them... - Hoka Carbon X 3 Road Running Shoes - Mens

I am 5'10", 170lb neutral runner who puts in 50-150 miles per month depending on the season (I live in Central Texas - summer running is lethal) and ambition (maintenance vs race training). My HOKA history - 1 pair of the original Cliftons, 3 pairs of the original Rincons, 2 pairs of the Rincon 2s, 3 pairs of the Rincon 3s, 1 pair of the Carbon X 2s. The best part of this shoe is the midsole without question. They are more comfortable now (about 150 miles in) than they were on my first run in them. Firm (relative to the Clifton and Rincons) yet still really cushioned/comfortable and more responsive (in my opinion) than the Carbon X 2s. The upper is very comfortable and definitely more breathable than the Carbon X 2s BUT, like a lot of other "professional" shoe reviewers have said, it is hard to get a good lock down with the upper (but it does allow your feet to swell). But because a lot of my runs are fairly straight, I am not making a lot of twists/turns in them so the lockdown isn't THAT big of a deal. The heel tab accommodates my heel and achilles better than the Carbon X 2 (rubbed a hole through the fabric in the heel cup) and I have never rubbed a blister in these shoes. I have used these shoes on anything from 4-mile tempo/HR runs to 11-mile ultramarathon training runs. My recommendation for these shoes - anything from fast 5-10K asphalt/concrete race shoes (where the course isn't too sinuous) to tempo/HR track sessions to half-marathon. Personally, not sure I would take them on 20+ mile runs. I got a lot more mileage out of my Carbon X 2s than I thought I would (probably between 400-500) and have already put well over 150 miles on my Carbon X 3s. Really really like these shoes and will probably get a second pair in the near future.
