I took my new leather boots that were too big and soaked them in a bucket of plain water for abt. an hour. Then....put them on my feet and wore them all day. Somehow, they molded to my feet just perfectly. this was recommended to me by a friend who'd tried this before on the advice of someone else. And, although I was very dubious, thinking the water would RUIN my new ostrich quill, expensive boots, I tried it cause boots were 'slipping' so much on the heels.....and problem was solved. It's kinda cool how the boots mold to your very own foot shape.
