Smelly Feet :(

DPR87

If you think it is the sweating that is causing the smell, you can try products to prevent sweating.
Perspi-guard seems to work well for people.

https://www.sweathelp.org/where-do-you-sweat/sweaty-feet.html might help. I used to suffer really badly but it is less severe these days. I can't however wear shoes or sandals without socks or tights etc. as feet sweat so much the foot just slips out and gets blisters. The smelling seems to have abated somewhat. I got some rubbing alcohol and put it in a cheap spray bottle and spray all my footwear once or twice a week, if worn. It treats the consequence but not the cause.

Apply surgical spirit to your feet daily, it helps stop them from sweating.
