Foot excercises to strengthen for barefoot vivos

[bpro2001]

I work in the oilfield and currently run birkenstock qs700 barefoot boots. They are nearly as flexible as my new vivos but I cam definitely tell I need to strengthen my feet more for the vivos. I am super familiar with the musculoskeletal system so PT'S please be specific of what muscles I need to strengthen and good excercises to do it. Any videos would also be helpful to ensure I am doing them right.
