If your work requires you to wear high heels everyday just stick with 1.5 inch. Use 3 inch and above for special occasion and events only. You can rotate your shoes by not wearing the same old shoes every day. You may also choose to wear high heels with wider heels; this can help maintain stability and balance for your feet.If you are fond of wearing these type of shoes, choose the ones that have straps. This can provide added support on your feet. Less material on your shoes means less support which may lead to poor balance.
