Reebok Nano X Cross Training Shoes, Mens 11.5, Light Blue, Red/Orange, White Shoes were very lightly used for about three months of working out... so probably worn about 40-50 hours total. No major damage or marks and still plenty of good squish/life left in them. The generation of Nano after this went back to a more minimalist design with less of a drop and they worked better for my feet, so these have just been hanging in the closet and now it's time to clean things out.
