They're perfect for pregnant women because they give arch support, helping your feet to stay in shape despite the hormones which would otherwise cause them to gradually flatten out.
They can be worn with any shoe, including flip-flops. What an inexpensive alternative to the $80 pair of flip-flops with arch support which I considered at the beginning of the Summer!
Too bad I didn't encounter these earlier on in my pregnancy. Still, they will be useful even after pregnancy, as my feet will appreciate the shape guidance as they harden once again.
