I agree with jburgh...if you can wear 4 inch heels, you should be fine. I have a couple of pairs of Choo heels, but wear mostly the flats or lower wedges. If you are going to be on your feet for a long time tho, you might want to have a little pair of ballet slippers to change into. I usually carry mine in the little Choo dust bag...How comfortable for Jimmy Choos? I just ordered a pair of 4" heels from his 24/7 line for my wedding. Am I going to regret it? We're going to have a more casual wedding in that it won't be a super long day and won't be dancing. I wish 24/7 meant that they're so comfortable that they could be worn 24/7! LOL
