Giro Factor Road Shoes



Like wearing your favourite slippers with cleats on

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Lightweight and stiffness is the order of the day when it comes to Giro Factor road shoes. Built on the same lasts as the range topping Prolight SLXs. the Factors are designed to suit virtually every foot in the land.

At this price point you've usually got two options for strapping the shoe to your foot – Velcro straps and buckles, or a dialled lace system like Boa. Giro have gone for the buckle and Velcro option but with a few tweaks. The lower steel buckle is in a pretty standard place but the upper buckle is positioned more to the centre to avoid pinch points and increase comfort. The straps themselves are actually part of the upper so as you tighten them you are pulling the top half of the upper over your foot rather than just thin straps, this removes any localised pressure points. The buckle itself has two positions, an upper and a lower, adjustable by the removal of a screw. This also allows a degree of flotation so that it settles perfectly in position on the top of your foot.

The uppers are Teijin microfiber, a manmade leather-style material which is very soft and pliable to the touch. It also looks very hard wearing. The toe and heel box are reinforced for longevity and shrug off marks and scuffs with ease. Plenty of small holes at various sections in the material take care of breathability and there are two sections of mesh at the toes to aid airflow.

Now for the pièce de résistance: the Easton EC90 carbon soles. These babies are not only immensely stiff and light but the stack height is just 6.5mm so your foot is very close to the pedal. The sole itself has a beam section running from the three-holed cleat area to the heel while the bare minimum of material is used on either side.

Out on the road you're certainly going to get noticed, even in these white, silver and red versions that are probably the most subtle. The Factors also come in a bling red & white or shiny black which scream 'look at me!' For a little extra you can get the Rapha Condor cycling team version.

The uppers take a little bit of time to bed in, as with any shoe, but once they have moulded to your foot shape they are hugely comfortable. The strap positioning and float on the buckle really aids comfort while still holding your foot secure for high power efforts. The most noticeable difference, though, is the weight, or the lack of it: these weigh just 255g for a size 42. I spend a lot of time riding fixed where the average cadence is about 100rpm; you can really feel the lightness compared to my usual Shimano shoes.

The heel cup is designed just right to offer support yet it's low enough to sit just below your achilles so there's no chance of aggravation on longer outings, while Giro's own customable insole allows you to attach a range of three arch supports depending on the shape of your foot.

All these comfort-adding attributes really make the difference on longer rides of 5–6 hours or so and while I did experience hot spots on my feet when out for this long, it is a small price to pay for the mix of comfort, lightness and power transfer.

Of course, over £200 is a lot to pay for a pair of shoes but these will pay dividends in the long run. The wipe clean nature of the Teijin material means they'll look good for a long time and as the uppers stretch and contour to your foot shape, the Factors are like wearing your favourite slippers with cleats on. test report

Make and model: Giro Factor Road Shoes

Size tested: White - Size 45

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Giro say, 'The Factor delivers ultimate power transfer with all-day comfort needed for long rides and maximum effort.'

That is pretty much bang on as they certainly deliver in both respects.

Tell us some more about the technical aspects of the product?

The Teijin upper material is breathable, hardwearing yet very supple, plus the Easton sole is a thing of beauty.

Rate the product for quality of construction:

There is not a stray thread, blob of dried glue or anything to make the shoes look anything but high-end kit.

Rate the product for performance:

Light, stiff and comfortable.

Rate the product for durability:

Hard to tell long term from just the test period but after 1000-odd miles all the marks and scuffs have rubbed straight off with a damp cloth. They've bedded in nicely as well.

Rate the product for weight, if applicable:

They would score a 10 but I know the Prolights are lighter

Rate the product for comfort, if applicable:

The odd hotspot from the sole is the only downside I experienced. This only affects you if you're really putting the hammer down.

Rate the product for value:

Expensive... but worth it in my eyes

After first throwing his leg over a race bike back in 2000, Stu's ridden more than 170,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him, he still likes to smash the pedals rather than take things easy.

Have just ordered a pair of these. Does anyone have a solution to the apparently 'cosmetic' grip pads on the soles? Have read 2 reviews where they say they are very thin, not replaceable and wear quickly. Don't want to be walking on bare carbon after a couple months!

Amazingly comfortable shoes. Worth every penny IMO!

Couldnt agree with you more, comfy from the very first ride!

I was adviced to get a half size larger than my regular size, which seemed to be spot on

Are they better than Sidi? Yes. I've had both and won't wear anything other than Giro now. They are perfect, particularly with the Supernatural insole.

They are so good I use the Factors on my road bike and the Code (the MTB version of the Factor) on my SS and MTB.

I have a pair of Factors - love them - the top strap is a buckle/ratchet, not the velcro strap shown in the picture...?

seanieh66 | 12 years ago

Why do the shoes featured above look different to Factors on the Giro site?  39

seanieh66 | 12 years ago

They look the mutt's proberbials, but are they better than Sidi Ergo2 Carbon Lites?  26
