The Next Generation Of S-Phyre
The Shimano Men's SH-RC903 S-Phyre Road Shoe is the next generation in ultimate performance. For the new 903s Shimano took the best and made it better, adding more ventilation, a more comfortable fit, and reducing weight.
From the ground up, the 903 starts with the same Shimano ultra stiff carbon sole (12 on their stiffness index) for unrivaled power transfer. For this iteration it's now ventilated at the heel and toe to keep your feet from overheating during your hardest efforts.
The fit is improved with a new 2-way BOA Li2 system to get your precise fit dialed in every time. The lacing has been updated to get you a more secure fit without hot spots, especially on the toe box. Combined with the supportive but flexible microfiber leather upper and redesigned anti-twist heel cup, this shoe is made to keep your feet locked in so you can stay focused on any sprint, climb, or descent you're pushing to the limit.
And with a claimed weight of just 225 grams in a size 42, the 903 comes in at least 10 grams lighter than the 902.
- Shimano Stiffness Index: 12 Carbon Sole
- Ventilated Toe and Heel

Perfect fit though a bit pricey.
I started racing with Shimano shoes back in the 90's and I returned to them with the first iteration of the 900 series with the 901. It was so comfortable that I decided to get the newest iteration due to some blemishes I had with a crash. This 903 version had the perfect fit with the half size. I had the wide version with the 901 but this wasn't necessary for the 903. The upgraded BOA dials give a snug fit giving my feet a secure enclosure without being restrictive. They worked with both thin and thicker socks. There are two choices with arch support and medium worked for me. White shoes are hard to keep clean. Not sure if I should treat it with a spray. So far, just wiping it with a damp cloth keeps it clean. Here's hoping it stays that way for my racing season this year!
