Giro Empire Men's Road Bike, Triathlon/Aero Shoes

Product Information

Keeping the carbon sole flat allows for what giro calls the ‘spillover effect’ : Colin Levitch / Future Publishing Giro quietly entered the shoe market in 2010 with a four-pronged product line-up comprising the Prolight SLX, Factor, Trans and Espada (women-specific). Giro’s strategy, based around lightweight materials, dynamic designs and affordability, helped it secure a significant slice of the market in a very short space of time. Too often, shoe companies neglect to include a well-designed footbed – a key contributor to both comfort and performance – so it's good to see that Giro have put in the effort here and haven't cut costs by including a super thin insole with barely any support. Not only does a well-supported foot reduce the risk of injuries in key joints such as the knees, but it also reduces the chances of hot spots developing due to the pressure being distributed over a wider area of the foot. These shoes are compatible with MTB pedal systems, which use cleats with 2-bolt cleats (SPD standard), e.g.: Shimano SPD, Time ATAC, CrankBrothers, CrankBrothers Race, Look MTB, Xtreme MTB, Wellgo MTB, Ritchey MTB. Also suitable for indoor trainers in gyms etc

When Giro first launched the Empire, it was the first shoe in decades to use laces instead of velcro, ratchets, or BOA dials. Initially many scoffed at the idea, but now just about every brand has its own modern version of the lace up cycling shoe. The Empire SLX is an evolution of the original shoe designed in collaboration with former pro Taylor Phinney, which uses a one-piece, monofilament, Synch Wire Mesh upper, providing plenty of airflow, complete with welded TPU panels for structure.This article begins by talking about how anomalous the Giro Empire SLX is because of its time on the market. I said it because there's no getting around that fact but that's not the only thing that makes the Empire SLX an anomaly. It's also an anomaly because of everything it can do. Phinney wanted the laces because he was looking for a way to keep his shoes as aero as possible. I'm not aware of any wind tunnel testing I can point to but laces minimise bumps and protrusions and Bradley Wiggins seemed to see some value in the design given he chose them for his hour record. It's also relatively easy to cover the actual laces which is something Swenson did, using a chopped up arm warmer, when he won the 2023 Leadville 100 mountain bike race. There's also another advantage to the laces though and that's what the SLX version of the Empire leans into. The laces work because of the stretch they have but they also work because of the low structure upper. People tend to focus on the inability to adjust the laces mid-ride and that's fair. That said, even during the multiple 200-ish mile rides I've done in these shoes, I've never wanted to adjust them. The carbon base doesn't wrap above the sole of your foot, the upper is responsive to pressure from your foot, and the laces will stretch. Tighten the Giro Empire SLX to fit when you leave the house in the morning and as your foot swells a bit it will find room.

The insoles are infused with X-Static silver fibres, which we found defended odour well. Because the fibres are woven into the foot bed, the antimicrobial properties are permanent, so will not wash away like some coatings and treatments do. Dampening enthusiasm? There were also initial worries about how to adjust the shoes’ fit during a ride but even that turned out to be a non-issue – at least provided you’re not a racer who likes to cinch your shoes down before a big sprint finish or climb. Simply take the time to dial in the fit before heading out and they stay comfortable for hours on end with virtually no loosening or hot spots even after six hours in the saddle. We noted just a bit of stretching during the first few rides but it’s been smooth sailing since then with no further shape changes noted, even after long rides in the rain. The laces also pose a problem for mid-ride adjustments; it’s not possible to loosen or tighten them without pulling over and sitting down. But we found, barring the first ride, that we didn’t need to make adjustments – owing in part to what Giro calls the ‘spillover effect’. Room to manoeuvre Despite the rise of more sophisticated fastening systems, laces are still very popular among cyclists and for good reason: laces are light, stiff, robust and stylish but on-the-bike adjustability is limited.In terms of fit, the Regimes have an almost slipper-like feel; the Synchwire upper conforms to every nook and cranny of your foot. Even with this softness and flexibility in the Synchwire, there is no stretch in the material, so once you tighten the shoes it provides the needed structure to prevent your ankle from collapsing.

For a shoe that appears to have minimal ventilation the Empires left us pleasantly surprised. The combination of perforated upper and vented sole enabled our feet to breathe, and the air flow – which increased considerably at speed – was certainly enough for sweltering days. Support where you need itWhile the rest of the world found themselves drawn to the Giro lace up shoes when a young, potential saviour of American cycling put them into road cycling race reports, I wasn't paying attention. Ten years later when another American phenom, Keegan Swenson, was again using Giro lace ups, this time for gravel racing, I still wasn't paying much attention. Instead, it was seven years ago watching the impossibly cool, slightly older Taylor Phinney hike through the snow in Therabout Reprise with Cam Wurf, Gus Morton, and Lachlan Morton. The four friends weren't racing but seeing Phinney with his bright coloured laces wrapped around the centre of his Giro shoes is a memory I haven't forgotten.

By keeping the the outsole of the shoe flat, not rolling it up around the edge of the upper allows for your foot to spill over the edge of the shoe. This means that when your foot expands, whether that’s from pedaling or foot swelling, it’s not pushing up against carbon, thereby eliminating hot spots and pressure points. While this comes at the cost of lateral support, the added support from the footbeds more than compensates.

The foundation of the shoe’s upper is a micro-mesh for a little stretch and plenty of breathability, then a Tijin microfibre reinforcement layer is applied. This gives the upper its structure, which is finished with a microfibre film top sheet — replete with padded sections. Where things really differ between the Empire and the Empire SLX is the design of the upper. While the Empire uses Teijin Samo microfibre upper to support the seven pairs of lace holes, the SLX shoe uses Teijin Evofiber SL Microfiber. The point here is to drastically save weight. The lightweight, highly ventilated design is not only the difference between the Empire and the Empire SLX but also the biggest update that came in 2019. The upper is light and airy but somehow tough enough for gravel racing. The laces aren't adjustable mid-ride but the stretch and low-structure upper mean they don't need to be. There are other lace up shoes but none of them are as light, and light shoes on your constantly moving feet feel great.
