I am in the same boat as you in regards to feet.
The feet sweat so much I get blisters due to the wetness. I have found the antiperspirant in combination with the foot powder does improve slightly--but does not take it away at some point. Additional socks yes, does help. Gotta hang the dry socks on the outside of the pack while you are moving. Then...change again. At some point you have to realize this is your life and it is a pain.
I have gone to ankle high Injinji socks with separate toes for a liner and Darn Tough outer socks.
I wear breatheable running shoes as an approach/return and carry the climbing boots. This does some to help I have found. Then when the climbing boots are required, I slip into them. Then when in camp, I wear the running shoes as camp shoes.
