As much as I love heels, got to admit, it's not a very good option to go shopping with. they are not as practical as slippers. I always opt for slipper if I'm going shopping. In fact, I actually opt for slipper MOST of the time! If I wear heels, I always bring a pair of slipper with me.
my handbag is always occupied with slipper! well that explains why I don't always carry small sized bag. hee. besides, it's light enough to be carried around.
be it flip-flop, slip-on or sandal. >_< I just can't stand getting blisters from wearing the heels. Plasters on my feet? I hate it so much! I'm narcissistic like that. haha. 'Beauty is Pain'? Comfort comes first PLEASE!
Trust me, it is always convenient to bring a pair of slipper with you. you never know what's going to happen to your (or to anyone's you're with) currently-wearing footwear. not to mention the comfort they provide!
