Racing flats as every day trainers. Recommendations?

If you start at 50-60mpw in flats running truly easy, your muscles and tendons and ligaments will adapt and you can handle anything. If anything props up, see a massage therapist and a PT who does dry needling for maintenance and you're good. I can hit 100mpw doing this.

Here's something kind of amusing - in early 2001, I discovered LRC. It was about 8 months after I started running. I quickly found out a few things - I needed to train in flats, stop heel striking, and run 180 steps a minute. I guess I had just came across certain threads that gave me the impression that this is what good runners did, and I wanted to be a good runner.

So I did both at once. Switched to flats and started midfoot/forefoot striking as well as increasing cadence to 180. In retrospect, it was the increase in cadence that made it almost impossible TO heel strike. The change was more or less immediate. Wearing flats caused some minor pain in my calves for about a week, but that was it. And I never looked back. And here I am, almost 17 years later. I'm glad I made those changes when I did; it made me a better runner.

And I'm still addicted to this damn website, even though I never learned another thing of value. Just kidding. Kind of.

I am poor (grad school) and don't replace my shoes until the soles have holes in the bottom. This is not an exaggeration... I volunteer coach and some kid asked me whether my feet got hurt because I guess I didn't pick up on it one time. Alas. So... take my statements with a grain of salt unless you're truly willing to push the limits of what a racing flat can take.

I've been wearing the NB 1400s for a few years, they last reasonably well. Run ~80 mpw and only use this shoe, typically get 1200-1600 miles out of each pair. I run mostly on pavement, but also a fair bit on crushed gravel and dirt. Older versions of this shoe were "better", but didn't last as long - upper would always rip near the toe joints, treads wore away making them useless on anything but pavement. Newer versions (v4, 5) last longer, but aren't as "racing flat-like." I've tried some of their other flats (Hanzo) but they don't last - soles get wrecked fast.
