I only ran twice because of the cold morning. The first run was only two miles and I could feel the difference in the shoes. Although the shoes felt softer, they caused discomfort in the feet. The second run was 4 km long. At the end of my run I was in pain on the climb. As the day progresses, the pain intensifies so much that walking becomes painful. I checked my return date and it was one day later than my return date. The shoes look great but I can't walk in these shoes.
