This year the emphasis is not on the height of the shoe in fact the heels are becoming lower, but the quality of shoe is more important.
Towering height may be fabulous for the catwalk, but we are talking about proportion to you, not the person next to you and not the models on high end catwalks.
Make sure that the shoes are good quality leather and my top tip is to put deodorant on your feet before, especially on hot days in sandals. It is the worst look to have toes grossly coming through the end of the shoe and on the floor. The antiperspirant will help stop the slipping.
Another top tip is to wear the shoes the day before, not for too long and see where the red patches and going to develop blisters, put on blister pads and don't use bandaids they just don't do the job. If you are going to be on your feet all day you have to be comfy.
When you wear your shoes around the house, put a pair of socks over your shoes as well as under sometimes, the last thing you want is wearing in your shoes and getting scuffs. Make sure all price tags are off your shoes as well.
Practice walking in the shoes as every pair is different and opt for stiletto heels this year rather than platform.
