Okay....I have been trying to locate manolo Bahnik Sederaby either in silver or black in my size. After making like a million calls, I found one. But I am wondering if 105 mm would look better than 90mm? Or 105 would hurt feet more than 90? That small of difference in height of heels can make a difference of comfort level on feet...I know that part...But I don't know if this brand's shoes never hurt feet no matter what height of heels is? I am only like 5'3"~5'4". So, I love high hills like 4"... Should I cancel order on 90mm and walt to get 105mm? PLEASE HELP! If I want to cancel the order on 90mm, I have to make a decision ASAP . Any advice, please?
