My method...... Wear cheap boots. Throw them away.
I used to do the spendy boot thing.
After years of unsightly footwear, I switched to these:

$19, lightweight, non-marring good-n-grippy sole, and they last way past the "look like crap" stage.
I add a $60 orthotic insole.....and they get relocated to new pairs as necessary. Super comfy.
I keep a stack of new ones in the closet.....6 deep.:thumbsup:
