Yes, your feet could get bigger during pregnancy -- and it’s often permanent -- but it doesn’t happen to everyone. This happens for a few reasons:

The foot is made up of 26 bones and more than 30 joints that are held together by a network of ligaments. During pregnancy, there’s a relaxation, or loosening, of the ligaments throughout your whole body. It’s your body’s way of preparing the pelvic joints for childbirth, and your fluctuating hormonal levels are believed to be what causes it.

Weight gain also contributes. Now that your body weighs more, it puts more strain and stress on your feet, which can cause the joints to widen. Got swelling in your feet? That’s a factor too.

If you’re freaked out about growing out of your favorite shoes, the good news is that there are a few ways you can reduce your chances that your feet will get bigger:

Wear supportive shoes. Be sure you have shoes that support your arches (think: sneakers, not floppy ballet flats) and shoes that don’t squeeze or pinch anywhere (stay away from those pointy-toe numbers that don’t give you any wiggle room).

Try compression socks or stockings. These can help control lower-extremity swelling.

Avoid excessive weight gain. Do your best to stay within the recommended weight gain range for your body type to avoid putting unnecessary pressure on your feet.

Try supportive insoles. These can be particularly effective if you already have low arches (“flat feet”). Ask your doctor or physical therapist if they might be right for you.

Do foot-muscle exercises. These moves can help strengthen the muscles that help support the foot: Standing on one leg, picking up marbles with your toes, scrunching a towel with your toes, standing or sitting and raising on your tiptoes and on your heels -- the tiptoe/heel exercise can help with swelling too!

Can’t tell whether your feet are just swollen or if they’re truly growing? Look for longevity. In other words, foot growth will last -- your shoes that feel tight on Monday at 10 a.m. will still feel tight on Thursday at 5 p.m. -- while swelling is bound to fluctuate. Usually, feet are more swollen at night than in the morning, and certain activities and positions, even your diet, can cause them to swell more or less. Compression stockings, the exercises above, regular massage and cardiovascular exercise (as long as your doctor has okayed it) can all help control foot swelling. You should also elevate your feet at the end of the day. While they’re elevated, point and flex at the ankles -- up to 50 times! -- to help bring excess fluid up from the feet and legs.

If your feet do grow, the good news is that it won’t hurt. The only reasons you’d have pain would be if you kept wearing shoes that were too small or if you had another foot problem caused by altered joint function (and if you did, that would be treatable!).

You’ll probably have to go up a half to a whole shoe size, and even though you may not want to give up those cute old Louboutins, it’s important to wear a shoe that fits you well (even after pregnancy) to prevent foot problems. There are a few pre-pregnancy shoes you may be able to get away with like a soft leather moccasin that has some stretch, but sorry, nothing stiff. Use this as a great excuse to do some shoe shopping.
