How to Measure for Shoe Size & SHIMANO DYNALAST 2.0 Fit

Place a piece of paper on the floor against a wall. Stand on the paper with your heel against the wall and mark the longest toe on the paper. Measure the distance from the wall to the mark. Note: Cycling shoes are meant to be form-fitting and on the snug side. If between sizes, size up. Sizing Note: Riders who currently wear a Standard fit can expect a roomier toe box, while those who previously sized up for extra width or toe room may prefer to size down by ½ size for a more precise fit. The new SHIMANO DYNALAST 2.0 Wide fit is noticeably roomier than both the previous DYNALAST Wide and Standard fits, offering increased width and a larger toe box. Women riders and anyone who prefers a snugger, performance-oriented fit may find the Narrow option provides the best fit.

When every watt matters and every adjustment counts, the all-new S-PHYRE SH-RC910 shoe represents the next evolution of SHIMANO’s flagship road racing shoe. Engineered as a complete pedaling system alongside the new SPD-SLR pedal platform, the shoe is designed for the world’s fastest riders and refined through extensive WorldTour feedback. The S-PHYRE RC910 delivers exceptional power transfer, an even more precise fit, and the lowest stack height Shimano has ever produced.

Sizing Note

Riders who currently wear a Standard fit can expect a roomier toe box, while those who previously sized up for extra width or toe room may prefer to size down by ½ size for a more precise fit.

Women riders and anyone who prefers a snugger, performance-oriented fit may find the Narrow option provides the best fit.

Focus on Every Detail

S-PHYRE

S-PHYRE is our flagship racing line that combines scientific-guided designs with professional insights to help you pedal harder, race faster, and see clearer.

Choosing the Right SHIMANO DYNALAST 2.0 Fit

Standard

If you've been happy with the fit of your current Standard DYNALAST shoes, the new Standard fit will feel familiar through the midfoot and heel while providing noticeably more room around the toes for improved comfort on long rides.

Wide

If you've worn Wide DYNALAST shoes in the past, be aware that SHIMANO DYNALAST 2.0 Wide is significantly wider than the previous Wide fit. Riders who truly need extra forefoot volume will appreciate the increased width, while others may find that the new Standard fit now provides all the room they need.

Narrow

Riders who previously rode SHIMANO's Women's-specific models or those who prefer an especially snug fit will generally find that the new Narrow fit offers the closest equivalent. The Narrow last maintains a lower-volume fit while benefiting from the updated toe shape and improved forefoot comfort introduced with SHIMANO DYNALAST 2.0.

Maximum Pedaling Efficiency

The S-PHYRE RC910 features a redesigned carbon hollow core sole that lowers the distance between your foot and the pedal axle, creating Shimano’s lowest stack height ever. The result is a more connected ride feel, improved pedaling efficiency, and more direct power transfer with every pedal stroke.

Precision Fit from Front to Back

Featuring the new SHIMANO DYNALAST 2.0 platform, the RC910 has been completely refined to match the shape of riders’ feet better. A wider forefoot, optimized toe box, and reduced toe spring decrease pressure across sensitive areas of the foot while maintaining the secure locked-in feeling demanded by professional racers.
