Do feet get bigger with weight gain?

That's very true, weight gain actually pushes the feet down and makes them spread out. It's always best to buy shoes that fit your current size to avoid painful shoe bites.

Obviously yes, your feet carry the weight of your whole body. When you put on weight, the feet flatten out to balance it, so your shoe size can go up by a number. Don't force yourself into your old shoes, buy a bigger size for now.

My feet used to swell up and feel tight in my sandals when my weight and blood sugar levels were high. For diabetics, foot size changes and swelling should be monitored carefully. Please eat low-glycemic foods to control fluid retention and protect your feet from nerve issues.

I totally panicked when none of my expensive heels fit me after I gained 12 kgs. I thought my bones had grown! But my doctor told me it's just fat tissue and flat arches from the weight, which is completely normal. Once I lost some weight, my old shoes fit perfectly again.
