Empire SLX Cycling Shoe

At just 185 grams, the recently updated Empire SLX Cycling Shoe from Giro is breathing some pretty rarefied air. Not many shoes on the market come within 100 grams of the iconic Empire, but it's not giving up anything in terms of performance, either. The new uppers are constructed from Synchwire, the same lightweight, low stretch, and quick drying material used on the range-topping Imperial. In fact, the new Empire uses the same upper and outsole as the Imperial, however, it trades out the BOA dials for laces, saving some 60 grams in the process and offering an even more personalized fit and the option of some color customization.

The new version is highly breathable and receives some mesh windows for additional airflow. The lightweight upper doesn't suffer from lack of stiffness though, and it receives additional structural support from its thermal-welded Teijin TPU sections. It also provides pro-level performance and a comfy fit right out of the box. If you haven't used lace-up cycling shoes yet, you should know that Giro uses special tubular-woven laces that are specially designed to remain tied, and there's also a lace garage on the top of the tongue to ensure they don't get tangled in your drivetrain.

Those uppers are attached to a refined Easton EC90 SLX2 Carbon Sole that receives additional resin for improved durability. This sole is amazingly stiff, and thanks to its unique construction, has one of the lowest stack heights available at a paltry 6.5mm. A low stack height means smoother pedaling and more efficiency and of course less weight. It's finished with stainless steel hardware and replaceable heel pads which both improve durability.

Between the uppers and the sole sits Giro's much-lauded SuperNatural FitKit, a long name for its user-tunable footbed. These insoles have swappable arch support inserts so you can tune the fit of your shoes precisely to the shape of your feet.

  • Giro's iconic Empire gets a makeover, proving lace-ups are here to stay
  • New Synchwire upper design increases breathability and durability
  • Thermal-welded Teijin TPU reinforcement boosts support
  • Tubular-woven laces allow for a custom fit and stay tied
  • Updated Easton EC90 SLX2 carbon sole receives more resin for more durability
  • Replaceable heel pads and stainless steel hardware improve longevity
  • SuperNatural Fit Kit insole with adjustable arch support dials in the fit
  • XT2 anti-odor fiber top sheet keeps odors at bay

This is my third pair of Giro’s. All have been comfortable and have a solid road feel. Six years and tens of thousands of miles and each still going strong. After my fifth ride in the new SLX l noticed two divots out of the toe on my right shoe. A first for any pair of my Giro’s. The new SLX is light with a glove like fit but the material is thin. Compared to my other pairs I’m a little concerned about the durability of this shoe.

Very comfortable going looking shoe. Air flow design will be perfect for the hot summer days in Sacramento, CA. I only ride in a Giro because of comfort and aesthetic style. Go Giro Go! (40 years of running have taught me the importance of essential gear - Giro fits the bill)

This is my third pair of Empires. I'm a big fan of the shoe. I really like the look and fit of this shoe. Living in Texas, it's great for the Spring and Summer months, as it's light and your feet don't feel like they are baking. That said, despite its light feel, I now have to question the durability of this particular Empire. After one low speed impact crash (less than 15 mph), the main casualty was my left shoe. The fall left a big gash in the side wall. They didn't even last me a year. Granted, I don't expect any gear to be invincible in a crash, however I would have thought they'd be more durable. Particularly at the price point you pay for them.


uffff God thank you I thought to buy some because they are beautiful but seeing that I stay with the tape or another better model

Super light, durable, and comfortable. Pick 2 because it’s doubtful you’ll ever find all 3. These shoes are 100-150 grams lighter than just about any other shoe on the market. Not surprised they don’t endure crashes well.

I really like the fit, feel and appearance of this shoe, but the nutplates in the sole do not allow the cleat to be mounted far enough forward for my foot on the pedal.

Who: I’ve been riding for more than 20 years and racing for most of that time. I race mainly Cyclocross but spend most of my time on the road and gravel. What: I bought these shoes based on simplicity: they’re light, they don’t have any complex closure mechanisms and, in my opinion, they’re a sharp looking shoe. They replaced the top level Specialized shoe SWorks 7 as I found the toe box too long/wide and struggled to get half sizing from different retailers (I was riding a 43 in Spec, I bought a 42.5 in Giro - much better fit). This is my second pair of Giro’s and I’m becoming a bigger fan each purchase. Where: I bought them right here on Competitive cyclist. I ride mostly in Marin, California. That said, I’ve recently moved here after working in Singapore for a few years and these shoes would be brilliant in the tropical Singapore heat. Ride impressions: You’ll immediately notice how light the upper on this shoe is. The impact is that it will feel flexible and almost ‘stretchy’. In my opinion this makes the shoe feel super comfortable. My feet feel like they have room to move but the shoe fits very close and very well. They are a bit ‘pointy’ but no more so than the volume fo other shoes on the market. They do not impact my toes. As a previous Bont rider these don’t feel in any way restrictive. The laces are wonderful. It took about 1 ride for me to get the tension right and now they’re great. I’ve never been one to adjust my shoes mid ride so... In summary: A lightweight, comfortable, sharp looking shoe.

Hi Rob! How do these fit? Are they true to size? You mentioned you used to wear Bont. Would you say that they fit the same?
