Road
If you’ve been walking all day, nobody is going to want to kiss your foot if you’ve been walking barefoot down a dirt road. Your feet are filthy, sweaty, and stinky. Nobody is going to want to kiss those feet.
Imagine kissing someone’s foot. Now imagine kissing someone’s foot after they’ve been walking down a dirt road for hours. It’s disgusting. Smell the stench of dirt and sweat wafting up into your nostrils as the foot approaches your lips. It’s wretched.

What was this person walking down again? Oh, that’s right – a road (ろ). They were walking down a dirt road.
Walking down a dirt road barefoot like this is a sure way to dirty up your feet. Feel the dirt, rocks, and twigs under your feet. The road is hard and dry and is not making your journey very comfortable at all.
