I swear, every time I find the perfect brand of minimalist shoes for running with my flat feet, they get popular, then to appeal to the growing crowd slowly morph into more of an Air Jordan bodyplan. It happened with Sauconys way back in the day and now I'm watching it happen again with Altras. I'm a bit too poor to buy my running shoes in bulk. If I'm lucky maybe I can get an older model off of Ebay for cheap.
And yeah, I love my toe shoes, but those are more for trail running or just doing errands.
I feel your pain. I don't do minimalist shoes, but I have the same issue with Brooks and Salomon, It seems like they can't go very long without changing or outright eliminating models.
I've had luck searching on Google shopping to find closeouts, as long as the change wasn't too long ago. It's usually a local or regional sporting goods store that is stuck with old stock and selling it off online.
