Footwear for limited smell

For extended bike tours, I use footwear to 1. ride my bike, 2. hike a bit, 3. walk around camp and 4. go for a shower.
In the past I used SPD-shoes for 1 and 2 and flip-flops for 3 & 4.

The problems are: a) clipless-shoes don't really feel at home on hiking trails and b) shoes/socks eventually smell like crazy. Also c) a slight tendency towards athlete's foot (wearing flip-flops in the shower was probably intended to avoid this…)
I tried socks with merino wool and spraying disinfectant on my socks and in my shoes. While that does seem to help a bit, I wouldn't consider it a solution. Also putting on wet socks in the morning is inconvenient and unlike the rest of the kit, socks in closed shoes don't dry that easily.

I think the major problem is when stuff doesn't fully dry (maybe actually the padding in the shoes more so than the socks).

So first question: Does anyone know if it gets better if the shoes have hardly any padding (road cycling shoes). Are there any good drying techniques? (carrying newspaper seems impractical, I might consider using a bit of rice?)

There are (or used to be?) sandals with cleats, especially those from Keen (commuter) seem interesting as I think good ventilation and no socks are a win. However: are they still available? How do they even feel? Are there other options – I am not sure, I can get the Keen sandals tight enough. There are barefoot shoes that seem better for hiking. But I would probably not wear neither for going in the shower.

I am excited to hear your ideas – has anyone tried touring in triathlon-shoes or bring along boot bananas?

I think I actually found a theoretically perfect solution for 1 and 4: https://lore.cc/ but if you have seen the price, you know why I say in theory…
