Thankfully, leather sneakers are the easiest to clean. If you’re using Crep Protect Wipes, open a fresh one, and use the soft side of the cloth to gently buff out any marks. If the dirt is stubborn, use the textured side of the wipe. If you don’t have Crep Protect Wipes, a Magic Eraser will also work well (but be sure to go gently because the eraser can be abrasive if you push too hard).
