After much request, we decided to tackle the midsole creases on pylon material, such as the Air Jordan 11. This procedure is not necessarily complicated, but it does require some patience and careful handling. You will need a fabric steamer for this project. We actually picked ours up at K-Mart for around $20. Some people may opt to use an iron, but the problem with an iron is the lack of precise control. For example, it is difficult to direct the heat at a specific spot with the iron. On the other hand, you can direct the steam from the fabric steamer on a central location.
