It's finally time to ditch the flats and sandals at the office and strut your stuff in some high-heeled boots. Fall calls for the return of the ankle boots and knee-high boots that show off your gams conservatively under a knee-length skirt, but how do you pick out something trendy and functional for those long days at the office? Here are some important tips for selecting the right style of boots for the office:

1. Avoid the stiletto heel boots. Stiletto-heel boots are among the top trends for shoes this season, but that doesn't mean they're appropriate for the office. While you might be able to get away with them under a pair of long black pants, they're sure to raise a few eyebrows when paired with a dress or a skirt.

2. Go for the chunky heeled ankle boots. Ankle boots are back in a big way for the Fall season, and you can find a variety of styles that are suitable for the office. Go for a chunky heel with a square toe if you want to stay comfortable and fashionable for those long days on your feet. Ankle boots are especially flattering with a knee-length skirt.

3. Save the over-the-knee boots for the weekend. Another hot trend for the Fall season are the over-the-knee leather boots. Definitely a style you want to show off at least once this season, but just don't make it at the office. This look is best reserved for weekends with the girls or date night.

4. Ankle lace boots are a definite fashion don't. No matter how much your inner rock star wants to play during the 9 to 5 hours, save the ankle laced boots for social hour. These boots are fun, flirty and make a bold fashion statement, but they're not a good match for the semi-professional office environment.

5. Try platform boots for casual Friday. If you're dying to wear boots this season but can't find a match for the conservative dress code, you may be able to get away with a wedge or platform heel boot (or bootie) on casual Friday. Take your pick of rich leather or soft suede in a variety of colors for a classy and trendy Fall look.
