Maternity leggings are intended to keep you comfortable while your body might be incredibly uncomfortable. The compression factor of any of these leggings can help with varicose vein pain and leg swelling. They also offer superior support to your growing belly and aching back. These are things you won't find in a regular pair of leggings. Also, with maternity leggings, you're not going to have to worry about them sliding down below your bump because you will be able to pull them over your bump and stay comfortable throughout the day. Maternity leggings are worth the investment because they are made with your changing body in mind.
