Nike Air Zoom Pegasus 38 27.5cm These are Nike Pegasus 38s that I purchased a few years ago. I've run about 100km in them, and I think they still have plenty of life left. The front underside of the left shoe is starting to peel. Please check the photos. I didn't notice anything in particular when running. If you have any other questions, please feel free to contact me. Thank you for looking.
