I have a pair of shoes with a mesh top. They are so comfortable they are now my only choice for just about every occasion. After 7 months, though, there's a problem - a hole above the big toe. This has happened to me with running shoes but not regular wear. A patch over the hole is not an option because it would ruin the appearance. Duct tape on the inside doesn't work. Anyone have any suggestions for how to repair the shoe mesh, and also how to prevent it from happening with a new shoe?
