You gotta give it time. Since the shoes are young and getting used to their new parent, you have to play with them and talk to them a lot. Soothingly. Bathe them in the finest powdered condensed milks and the slickest, vanilla scented personal lubricants. Hourly. In a few months, you’ll have a nice, obedient pair of soft shoes.

Treat problem areas. With sandals and high heels, an edge or seam may painfully rub against the foot. But there is an easy home remedy,  “Use an emery board to rub down a rough edge,”  “Or take a white candle and rub the wax onto [the problem spot] to soften the leather, whether it’s inside a boot heel or a sandal.” Leather conditioner or saddle soap also might work, although not quite as effectively.

So you need to break in that new shoes quickly just like what I’m recently do to break in my new leather sandal which cost me a lot. I don’t know if it’s design problem or just the size matter, it’s rubbing my rear feet very hard and don’t seem to be a little improvement after a few days.

Maybe next time I should pick the shoes that with fish front and hollow rear, so that would cause me no rub anymore. En : ) Rich people would make custome shoes according to their feet size, how great of that. A cosy shoes is very important to your overall health and comfort too. Quite aware of that, so I was very careful of buying new shoes.
