I leave my work shoes in my office locker and usually wear rubber shoes going to work and back home. Well, walking the from Mega Mall to San Miguel Avenue can be a bitch with your leather shoes so why make the sacrifice when it's not even Holy Week? It may not be smart-looking to wear rubber shoes with your barong---but I don't care---it's not your foot at a discomfort.
However, with the rainy season in full swing, I shifted to wearing my sandals to work.
Mental note: DON'T FORGET TO BRING SOCKS.
