They fit into place with no problems and no issues with the installation process. I ordered my exact size, 8. I lost my previous pair after a year, if I didnt lose it it would probably have lasted me years. And that was before I decided we should return the ones that were awful. The quality seems very nice. They are a bit heavier than I expected but I believe that is because of the sole being so dense. I received the package on time and it works very well. UPDATE: 06/18/19. El articulo cumple con su función, parece de baja calidad pero la verdad es un buen producto. There is also a chip on the outside back corner.
