Do Not: Wear Stilettos
Heels are fine during pregnancy, but it is best to avoid stilettos with a heel of three inches or longer because your center of gravity changes. This causes unsteadiness and can lead to injuries.
If you must wear heels, then opt for wedges, platforms, or kitten heels. These are easier on your feet and ankles and are safer to wear. Your best option may be a pair of flip flops, though.
