https://www.somfootwear.com/ I'm not sure what type of running shoe you prefer, but these are a minimalist shoes made in Colorado. My first pair are in excellent condition after two years. I like them so much I bought a second pair just for non running activities. When the soles finally wear out they will re-sole for 50$ plus shipping.

Happening in Houston already to a lesser extent. Options are limited, many companies aren't making new policies.

Not as much, no. From my experience massive conglomerates seem to be a Japanese / Korean thing. I used to have a Yamaha dirt bike and keyboard!
