These are authentic running shoes recommended by a specialty shop. I bought them because the specialist staff recommended them for their cushioning, which is ideal for lower back and knee pain. The sole is made by Continental (the same manufacturer used for F1 tires and Mercedes original tires). They are recommended for marathon races, etc., but I was using them for walking. They were expensive shoes, but how about getting them at a bargain price? *The box is not included to reduce shipping costs. Size: 25.5cm *Of course, these have been used, so please refrain from purchasing if you are concerned about minor stains, signs of wear, or the fact that they are used.
