They've now decided that it is acceptable. I'm excited to be able to wear toe-less shoes but wonder what kind of professional guidelines should I follow. Is there any types of shoes that I should still avoid? Whitney Answer: Dear Whitney, It's quite savvy of you to make those distinctions between open-toe shoes that are appropriate and those that are not. Obviously, you are in tune with professionalism and are aware of the pitfalls of going to the lowest common denominator of what a company allows. For starters, the most professional open-toe shoe has a closed heel and does not reveal that much of the toes. Basically, it is a classic pump with an open toe. Clearly, this style comes closer to embodying professionalism than sandals do. And they are quite classy. Avoid wearing any Birkenstock styled shoes or those that bare any resemblance. They are just too casual for a work environment. On that note, it's best to avoid ultra flat sandals as well. They clearly communicate leisure time. Stick with a shoe that has at least a little heel and some substance, not necessarily clunky, to continue to convey professionalism. Ultra strappy, spike-heel evening styles are not appropriate for the workplace either. I doubt that I need to remind you such dangerous don'ts as wearing thongs or flip flops. Or those sandals that have a special place for the big toe. Speaking of toes, be sure to keep yours well manicured and preferably polished when wearing open-toe shoes in the workplace. Bare toes at the office opens the door for maintenance habits and toe secrets to be revealed. Best of luck to you, Sherry Maysonave Also see: Shoes for navy suit Should I wear boots to work?
