I've owned multiple Shimano, Specialized s-works, Lake and Quoc bike shoes. I really didn't think anything could top the older s-phyre I had in fit and aesthetics. After having these for about a month I do believe Shimano did an outstanding job on the 903. Hands down my favorite cycling shoe ever with great power transfer and ZERO hotspots, which is really rare for my odd shaped feet (Have a wide toe box plus the outside/anterior joints that protrude outwards). Very happy my need was timed with the latest model release, not the least of which is due to the all white color way (no black or champagne colored heel). Only thing up for longer term debate is the fabric on the middle of the toe area and how clean it will keep. The prior model did not have this, but I can definitely say these are more breathable for it!
