I've got a pair of Merrell hiking shoes and some basic heavy duty insoles from Dr. Scholls. My only issue was getting used to the lack of material under the toes, causing them to angle down a bit.
I recommend starting with the insoles first, see if they provide the support you need. If that doesn't help, I recommend escalating to a doctor. They can provide better shoe recommendations than us randos on Lemmy.
It's an indoors office plant. If it ends up leaving the pot, it'll likely end up getting rolled over by some chair wheels.
Given the soil mix I used, it'll likely be very happy for the rest of its life.
