Giro Road Shoes
Giro road cycling shoes have earned their reputation the hard way - through genuine engineering choices rather than marketing gloss. The range spans from featherlight race slippers with Easton EC90 carbon outsoles to relaxed endurance options with BOA L6 dials, so whatever your Sunday morning looks like - a hammerfest or a long rolling century - there's a model built around your actual needs.
The construction story starts with the Synchwire seamless upper, a one-piece synthetic wrap that holds your foot snugly without creating pressure seams. Pair that with the SuperNatural Fit Kit's interchangeable arch supports, and you've got a shoe you can genuinely dial in to your foot shape rather than just accepting what's in the box. Aegis anti-microbial treatment is built into the lining too, which matters more than you'd think after a long wet ride.
Giro's 3-bolt outsoles work straight away with Shimano SPD-SL and Look Keo setups - the pedal systems most UK road riders are already running. If you're comparing options, Shimano road shoes and Fizik road shoes sit in the same conversation, but Giro's fit customisation and lace-up heritage give them a distinct identity worth understanding before you choose.

Upper Tech and Sole Stiffness: Synchwire and Easton Carbon
The Synchwire upper is one of those details that sounds like small print until you've worn a shoe without it. A single-piece synthetic construction means there are no overlapping panels pressing into the top of your foot mid-climb. It wraps cleanly, breathes well, and holds its shape under load - so when you're driving hard out of a corner or grinding up a long drag, the upper isn't flexing away from your foot. That matters for power transfer, but it's also just more comfortable over four hours.
Below that, Giro structures their sole options around two Easton carbon composites. The EC90 is the stiffer of the two - genuinely pro-level rigidity, the kind where you feel every watt going directly into the pedal rather than dissipating through a flexy platform. It suits riders who spend most of their time at pace and want nothing wasted. The EC70 sits a step down in stiffness, which actually makes it the better call for longer endurance rides where a small degree of compliance reduces foot fatigue over the final hour. Neither is a compromise - they're just calibrated for different efforts. Think of EC90 as race day, EC70 as the Sunday double-metric.
Power transfer is the headline, but ventilation is worth flagging. The Synchwire's perforated zones and the carbon sole's open construction keep airflow moving across your foot - useful on humid summer climbs where heat builds fast inside a closed shoe.
Understanding the Giro Fit and Range
Giro's last runs slightly narrower than some rivals - Shimano in particular tends to offer a roomier toe box as standard. Most riders with a standard foot width find Giro fits cleanly true to size, but if your feet are on the wider side, it's worth seeking out the High Volume (HV) versions before assuming you need to size up. Half a size up is sometimes the right move, but it can introduce heel lift, which is its own problem.
The biggest fork in the range is the closure system. The Empire uses a traditional lace-up design - a proper throwback that Giro more or less revived for modern road use. Laces give you infinite, even tension across the full width of your foot, and there's an aero tidiness to it that BOA dials can't quite match. It's a faff to adjust on the move, though. You're committing to your tension before you roll out.
BOA-equipped models like the Regime use twin BOA L6 dials, which let you tweak fit one-handed while you're actually riding. Useful on a long day where your feet swell slightly in the heat, or if you need to loosen off quickly at a café stop. The micro-adjustment is genuinely precise - not just coarse tightening. For most riders doing mixed-distance road riding rather than racing, the Regime's flexibility is the more practical choice. The Empire is for those who've thought about it and decided they want laces.
Whichever model you go for, check whether it includes the SuperNatural Fit Kit. The three interchangeable arch support pads - low, medium, high - let you match the footbed to your actual arch shape rather than accepting a generic flat insert. It's a small thing that makes a real difference if you've ever had hot spots or numbness on longer rides. If you're also looking at Specialized road shoes, their Body Geometry footbed system works on a similar principle, so it's worth comparing both before committing.
Riding mixed surfaces or gravel? That's a different shoe category entirely - take a look at our Giro MTB and gravel shoes page for off-road options. And if you need replacement BOA dials, laces, or heel pads for an existing pair, the Giro accessories section is a good starting point.
UK Riding Conditions and Looking After Your Shoes
British riding means your shoes will get wet. Regularly. The Synchwire upper handles this better than a leather or mesh construction - it doesn't absorb grit and water in the same way, and a quick wipe with a damp cloth after a mucky ride is usually enough to sort them out. They won't dry instantly if they've been submerged in a puddle, but they don't hold moisture for long either.
For proper winter riding, a road shoe - even a well-made one - needs overshoes to stay comfortable below about eight degrees. Don't expect the shoe itself to insulate. What you can do is size slightly up if you're planning to run thick merino socks in the shoulder seasons; a half-size of extra room makes a real difference when you're in October and the warmth-versus-fit debate starts.
BOA dials need a quick rinse after gritty or wet rides. Debris in the dial mechanism is the most common reason they stop ratcheting cleanly. Run water through the dial, click it back and forth a few times, let it dry - that's genuinely all it takes. Most BOA dial failures are just dirty dials, not broken ones. Giro, like most brands, will replace faulty dials under warranty if you contact them directly, so don't bin a pair of shoes over a stiff dial before checking that first.
Cleat compatibility is straightforward. Giro's 3-bolt outsoles work with the standard Shimano SPD-SL and Look Keo systems that cover the vast majority of UK road setups. If you're running a different system, check the outsole spec on your specific model, but for most riders this won't be a consideration. Round out your kit with a look at Giro helmets - the brand's fit philosophy carries across categories, so if the shoes work for you, the lids often do too.

Giro Road Shoes FAQs
Do Giro road shoes fit true to size?
Generally yes, but the toe box runs slightly narrower than brands like Shimano. Most riders with standard-width feet find their regular size works well. If you have wider feet or intend to wear thicker winter socks, either go half a size up or look specifically for Giro's High Volume (HV) models, which offer a roomier fit without sacrificing heel hold.
What is the difference between Giro Empire and Regime road shoes?
The Empire uses a traditional lace-up closure - favoured for its aero profile and the even, fully customisable tension it creates across the foot. The Regime uses twin BOA L6 dials, which allow one-handed micro-adjustments while you're actually riding. The Empire suits riders who want to set their fit once and race; the Regime suits longer days where on-the-fly tweaks are genuinely useful.
How do I adjust the arch support in Giro cycling shoes?
Shoes with the SuperNatural Fit Kit include three arch support pads - low, medium, and high. Remove the insole, peel the current pad off the velcro strip underneath, and press on whichever height best matches your arch. It takes about thirty seconds. Start with medium if you're unsure, and move up or down based on how your foot feels on a longer ride.
