My friend and I have to attend a work conference from the company we work in usa. We live in a whole year warmth weather country so we are used to wear high heels formal sandals with work outfits. Now this conference is in the states in the san francisco bay area this summer and is a morning conference and we wonder if is right to wear that kind of shoes there or if is neccesary another type of shoes. What to wear in general.

Play it conservative and wear business attire…Pant or skirt suit, or matching jackets and skirt/pants with closed toe dress shoes.
