Typically $60... that's how much I try to pay for my $120 sneakers, for example.
For the rest, unfortunately, in my experience, paying over $100 doesn't necessarily mean that the shoe will last, so right now I have no idea how much I would pay, lol. My $130 winter boots didn't last a season last year, but the ones I paid $60 for this year are still going strong, so who knows. But I still love my $120 sandals from last year.
I need to buy hiking shoes at some point though... otherwise I mostly wear sneakers...
