I find that I have been buying sneakers more and more frequently in recent years it's all because they get damaged so quickly, especially interior of them, a lot more quickly than decades ago. In late 90s or early 2000, my sneakers could last for 8-10 years without problem, and without any care. Are they now using materials of poorer quality because of more vigorous business competition? Is there any tips to keep the best condition of my sneakers? Should I wipe them with damped cloth regularly? Now, I don't give any care to the sneakers.
