You probably know that wearing peek-over-the-waistline panties is a big no-no, but there are other occasions where it's important to be shoe appropriate. If you're hiking, you want shoes that will give your feet solid support. When you're near water, you need shoes with soles that will grip wet surfaces. The occasion should be part of the equation when you're deciding on what shoes to wear. Even though you'd look amazing in those 5-inch heels, does it really make good sense to wear dangerous footgear to a pool party, barbecue or park visit? Stay stylish, but be safe, too.
