Wearing your heels half size larger does help prevent swelling. We noticed while watching Golden Globes arrivals, that many celebrities choose to wear shoes that are just a little too big. This is to help prevent blisters and to stop their feet from swelling. But walking around in shoes that might fall off sounds pretty uncomfortable, plus that does causes blisters in other ways (like on the back of your heel). What to go with? Swollen feet and blisters or blisters and shoes falling off, too...so it’s a wash? But it doesn’t have to be. Wearing heels half size up (if you are not between sizes) with Solewells™ definitely prevents friction and blisters. The shoes won’t fall off, and your toes and soles are feeling great! It’s a win-win.
