This is my device designed to prevent and stop creasing in sneakers. It will also effectively reduce the appearance of already set in creases. Please follow the instructions included in The DeCreaseR packaging for best results and the most comfortable fit. The DeCreaseR is best used when placed for long periods of time in 1 pair of sneakers. 5 packs and 20 packs are available to accommodate your collection. Any issues with this product should be emailed. However after 9 years in production, this product remains unchanged and effective on nearly all types of sneakers. All sales of this product are final. This product ships immediately. Occasionally back-orders occur, you will be emailed to advise of any delays should they occur.
