No its not your imagination! Expert podiatrists estimate that nearly all mothers will be wearing shoes 1/2-1 full size bigger after they've had children.
This is because relaxin is a hormone released during pregnancy that loosens ligaments and tendons to make birth more comfortable. But this also causes your feet to spread. So if you're planning on buying some expensive new shoes, and why not, you might want to delay the investment until after you've had your children....!
Souls insoles are designed by expert Podiatrists to support your feet in pregnancy to hold the min a healthy position and counter the effects of relaxin whilst keeping your feet comfortable.
