Interesting article that, for some women their feet are bigger after pregnancy.
"It’s common knowledge that quite a few things get bigger after pregnancy (ahem, post-pregnancy hips). Now a new study shows that a woman’s foot size is something else that may be forever altered as well.
Researchers at the University of Iowa measured the arch height and foot length of 49 women during their pregnancy and five months after they had given birth. On average, researchers found that the arch height decreased, and in turn, the foot length increased by 2 to 10 millimeters during this period. According to the researchers, 60% to 70% of the women in the study had longer feet and shorter arches after childbirth."
