What types of shoes should I wear while pregnant?

Comfortable ones! Our feet tend to swell and spread with the extra weight. Don't be surprised if your usual footwear becomes too tight. Heels can give you more backache problems because of the way you have to hold yourself when you have a big belly and breasts. Good supportive athletic shoes are your best bet.
Comfortable. Avoid heels. Wear comfortable shoes with good arch support.
Hmm. Whatever you like and what feels comfortable.
