I'm a sandals fan. I go for comfort.
I remember the movie "Hanggang Ngayon" starring Regine Velasquez and Richard Gomez. Richard's father told him there that the right partner is like a pair of tsinelas (sandals). Even if you wear shoes at work or at play, you'd still want to wear those comfy tsinelas. You'd always yearn for your tsinelas.
Another foot-relationship analogy comes from my ex-boss. He said that marriage is like shopping for footwear. Dating and pre-marital relationships are like trying out the shoes (or sandals, what-have-you's). Marriage is the actual buying. No return, no exchange.
