I proudly wear my flip flops everywhere - you name it : I'll take it to the wet market, to the beach and even to the shopping centres or mall. My only exception is the office - least I risk being shouted at by my boss for looking unprofessional in flip flops! But I do keep a spare flip flop in the office in case my feet gets tired, I switched to wearing them.
If you open your eyes wide enough, you'll notice that there is a flip flop to suit all your personality! They are not only comfortable but the new ones even comes with funky colours and design!
