Article in English: Keep in mind that, no matter what you do to the inside of your shoes, they'll still be about the same size on the outside. This can unfortunately sometimes lead to posture and gait problems. When you're wearing an oversized pair of shoes, it's important to maintain good posture to compensate for your "bigger" feet.

Try to avoid using too-big shoes for longer treks like day trips and hikes. You will spare your feet the discomfort of blisters, cuts, and sore spots caused by big shoes sliding around as you walk. More importantly, you'll also reduce your chance for injury. Ankle injuries (like painful twists and sprains) are more likely in shoes that are too big. This is especially true in athletic situations. This may seem obvious, but it bears mentioning: the tricks above will only go so far. If your shoes are more than one or two sizes above your normal shoe size, no amount of padding will help. Don't risk pain and injury just to wear a pair of new shoes. In these cases, you'll want to switch for a better-fitting pair of shoes — even an old, worn-out pair is usually a...
