Sweaty feet and shoe smell, what actually helps?

My feet sweat a lot, especially in closed shoes at work, and by the afternoon I am very aware of it. It knocks my confidence more than I would like, particularly somewhere like here where feet are something I genuinely care about looking after.

I already wash daily and change my socks, so I feel like I am missing a step somewhere. What actually keeps things fresh through a long day in shoes? I am after real routines rather than just spraying something on and crossing my fingers. Anything that has worked for you would honestly mean a lot to me, thank you.
