70% of Women Go Up a Shoe Size After Pregnancy.....
Pregnancy may increase a woman's foot size, a change that appears to be permanent, according to a new study.
Researchers measured the arch height and foot length of 49 women during their pregnancy and five months after they had given birth. On average, the women's arch height decreased, and in turn, their foot length increased between 2 and 10 millimeters (about 0.1 to 0.4 inches) — during this period.
Overall, about 60 to 70 percent of the women had longer feet and shorter arches after childbirth, the researchers said. Eleven of the women reported changes in their shoe size, the researchers said.
This is due to hormonal effects and the changes in your arch height can cause you all sorts of issues like knee, hip or back pain. That's why we developed Souls - insoles designed by expert podiatrists to support your feet during pregnancy to minimise this effect and help you stay fit, active and healthy during pregnancy.
