hmmm..
i think maybe ur bf think that girls in heels are more sexy and of course more attractive.
my bf always tell me he likes girls in those heels with lots of strips..
aahahhahah~~
personally i like to wear heels!! it makes me more confidents and look thinner... hee hee
but depends on where am i going la..
if got dinner with him or working then i will wear heels..
if go shopping i will choose flat or wedges..

i think that tell him ur feeling is the best way..
say that u would love to wear heels but it just too tired and painful to wear it to shopping and la la la..
