I’m it sure what “dangerous” means here. To each his own but zero drop for me has resulted in fewer running -related injuries. I love them. And for me, the ramp up time was nonexistent. It took maybe a couple runs to get used to it. I find it much more natural than a big drop shoe.

To OP, I developed PF long after I started using Altras. I didn’t find them either burdensome or helpful in the recovery process.
