When you live in a warm climate like Mazatlán, sandals are the order of the day. I think I have worn shoes maybe five times in the last seven months!
The streets are dusty and the dust and dirt gets everywhere, including your sandals!
So, when I get into the shower in the morning, most days I have a sandal scrubbing session before I actually shower myself! I have a scrub brush waiting for that purpose, and shampoo does a good job getting them clean.
It’s just one of the many things I had never thought about before we moved here.
