I got mine around 2012 (but not the toe version) and quickly found out that running in them for more than 15 minutes makes my feet hurt, with no sign of a training effect.

But they still serve me well as gym shoes with a very low packing volume (great for business trips).

I've been running barefoot (real, but sometimes also in 'barefoot' shoes) on and off for years, and my feet quickly got used to it.

But then, I've always had a forefoot strike.

I also do a lot of barefoot walking.

However, the first few times I definitely ran for less than 15 minutes. That seems like overkill when getting used to barefoot running. I was sore enough in my calves for days from five minutes of running the first few times.
