Shimano RC5 Shoes Review

In the mid-range category, the Shimano RC5 shoes incorporate some of the features found in the brand’s higher-end models, which sell for up to 2.5 times as much. Although they don’t quite match those models in terms of performance and comfort, they’re still stylish, with a retail price of just €139.

In the Shimano catalog, the new RC5 shoes are positioned at the same level as the 105 drivetrain and pedals, while the RC7s are on par with Ultegra and the S-Phyre with Dura-Ace, according to the Japanese brand’s nomenclature—and based on the pedals recommended for use with these otherwise very stylish shoes. As with the 105 groupset, these mid-range shoes directly benefit from technologies developed for higher-end models, which are adapted here into a more affordable version.

These mid-range shoes directly benefit from technologies developed for higher-end models.

This starts with a minimalist midsole, positioned between the outer layer of carbon-fiber-reinforced nylon and the insole, which is slightly more elaborate than a simple insole. This helps keep the shoe thin, thereby reducing the distance between the foot and the pedal to stabilize the pedal stroke and optimize power transfer. The last follows the Shimano Dynalast design, which is intended to improve passage through the top and bottom dead centers of the pedaling cycle, thanks to the sole’s unique curvature, similar to the S-Phyre. The shoe is then secured using a Boa L6 ratchet system with a nylon cord, wrapped around a wraparound upper that closes over the foot like a sock. A Velcro strap at the front helps stabilize the forefoot if necessary. The heel features a semi-rigid shell and a highly enveloping, fully padded upper for excellent support without any discomfort. Finally, numerous small holes reveal a mesh section on the upper to ensure ventilation, and there is also an open mesh panel under the front of the shoe.

Easy Adjustments

The low profile of the sole and its width at the cleat placement allow you to easily find the right fit. The sole provides enough room to customize cleat placement without the cleat extending beyond the edge on either side, as is all too often the case with smaller-sized shoes. The sole’s profile and height are similar to those of the S-Phyre, although here you feel as though you’re riding slightly higher (perhaps just 1 or 2 mm) while pedaling.

Comfort and stability are therefore well assured while pedaling, just as with the brand’s high-end shoes.

Comfort in Question

Although pre-shaped and featuring slight reinforcement at the arch, the insole is comfortable but a bit flexible. It lacks a bit of support for feet with a pronounced arch, which enhances the flexible feel provided by the outsole. When wearing custom, semi-rigid insoles, the shoes feel significantly sturdier.

The carbon-reinforced nylon outsole is rated at a stiffness index of 8/12. In practice, this means that when standing still, you feel a slight flex at the cleat and a slight twist under the sole at the heel. While pedaling, this is only noticeable during intense efforts or when pedaling hard, where you feel a slight flex but cannot say for certain that it detracts from performance. In fact, it’s more during energetic accelerations that you can feel the base of the heel shift slightly, but the heel is held so securely in other respects that it isn’t really bothersome, even when aiming for peak performance.

The perceived stiffness also depends on the upper and the quality of the fit. Although exceptionally well-finished, this synthetic leather and TPU upper is unfortunately a bit too stiff to allow for very tight lacing. Shimano’s efforts to minimize internal seams are evident, but where the upper wraps around the foot, a relatively narrow foot may experience some creasing that eventually becomes uncomfortable by restricting blood flow to the top of the foot. The top of the upper also extends quite high up the instep, which is excellent for support but can restrict ankle movement if the laces are tightened too much.

The Boa L6 dial offers micrometric adjustment, but only for tightening. To loosen the boot, you must pull on the dial to completely release the system and loosen the nylon cord in the cable guides. If the boot feels too tight, you’ll need to loosen it completely before tightening it back up one notch at a time. This type of closure is very firm and secure. And since the upper doesn’t seem to stretch or lose its shape, the support for the entire foot is very effective.

A high-quality finish

A less rigid outsole, a less sophisticated insole, less flexible materials, and a simplified Boa dial account for the price difference compared to the higher-end models. It’s also worth noting that the heel pad is not replaceable here (but who has ever actually needed to replace a heel pad on cycling shoes?).

In terms of build quality, however, Shimano really delivers with the RC5, especially in this price range. The shoes come in three colors and sizes 36 through 50, with very well-executed seams between the different sections, flat-lock stitching, and well-placed ventilation. The RC5s really look a lot like high-end shoes. They can also maintain this great look for a long time, thanks to materials that are easy to wash.

On the road, as we mentioned earlier, the relative flexibility of the sole is hardly noticeable unless you’re riding at a high competitive level. The support is excellent, and the fit is always secure regardless of foot shape. However, comfort will be best for feet of average width, which won’t require the laces to be tied too tightly. This is because, over time, excessive tightening can lead to discomfort, causing temporary loss of circulation—which in turn can result in tingling, a sensation of cold, or, conversely, a feeling of heat in the feet.

Although less comfortable than the higher-end models in the lineup, the RC5s are, in our opinion, best suited for recreational cyclists riding medium distances; however, they do offer sufficient performance for taking your first steps in competition. And they come with style to boot—which is rare at this price point.
