Yes, her shoe selection for stone walking, or walking stoned, either one, it was an absurd choice, but typical for one who is convinced she walks on water.
I’ve traveled a lot around Europe and you see a lot of Americans who show up with stupid ideas on tourist walks or hikes.
It’s like the act of carrying around a bottle of water and hydrating yourself. Or having some fruit in your backpack to ensure no blood-sugar issues in the middle of your walk. The shoe thing always amazes me...people always seem to want comfortable shoes with no tread on the bottom.
