Giro Prolight Techlace Cycling Shoes
9 10

Giro's Prolight Techlace Cycling Shoes are ultra-light, attractive top-end shoes that will make a big dent in your wallet but are a worthy purchase if you can justify them.

Giro has been the leader in reintroducing what some might see as an antiquated way of securing your shoes, and these flagship Prolight Techlaces are the latest in the line from the Californian company's range of top-end footwear.

A pretty ordinary looking box opens to reveal the treasure within: a travel bag, the shoes themselves in all their bright crimson red loveliness, a bag of parts and an instruction manual. Seeing a manual with a pair of shoes threw me to start with, but it did prove useful as it gives easily digested guidance on what to do with the bag of parts, containing the adjustable footbeds and a set of titanium cleat bolts.

The shoes themselves are indeed remarkably light, feeling unbelievably featherlike in the hand, but that's no surprise when they only weigh a scant 193g per shoe for a size 46. The quality of construction is obvious to the eye. The sole is made from Textreme carbon; the science is rather complicated but the upshot is that it's lighter (20% on average) and stronger than your standard carbon. It's also used by Felt on its top-end bikes and PRO uses it for its eye-wateringly expensive wheels.

As regards the upper, I can honestly say I haven't seen anything like it before. The skeleton – literally, as there are many cutouts – of the shoe is made from ultralight Techmesh, then covered with a Teijin TPU top layer, which has an unusual feel to it and is opaque. Yes, really. Choose your socks carefully as where the cutouts are you can see what's underneath. Again, baffling science behind the materials, but it looks good, vents well and is easy to clean.

In the ongoing race for lightness it would seem that going back in time is the key, as more and more shoes hitting the market lately are dropping the ratchet, full Velcro enclosure and even now the Boa dial in a quest to save a few more grams. With the Prolight Techlaces, Giro has taken the full lace setup from its Empire shoe and modified them to the enclosure we find here. Consisting of segmented laced sections with Velcro attachments at the ends rather than two continuous laces, as in a traditional shoe, it offers adjustability at three points similar to a lot of full Velcro closure systems that have been around for years, but reducing the weight by a good margin. In use I found them to work well, getting the fit right quickly before getting on the bike and then easy to adjust when on the move.

I usually use a set of custom made footbeds with any cycling shoes I wear, but after reading through the manual and taking a look at the included adjustable footbed I thought it was worth a try. Far more naturally moulded at the heel than typical, they offer three different arch supports from minimal to high (which I generally fall under). The manual guides you though determining which would be best for you, but I opted for the largest size based on my custom pair and left them in for the first couple of weeks.

They performed very well indeed, not feeling too far off my customs and certainly not giving me any real issues, only proving not perfect on day-long rides when I did get a little discomfort. I have been wearing custom footbeds for six years, though, so it shows they did well in the interim and if you currently just use whatever your shoes came with then they are likely to be a bigger benefit.

Wearing them in general was a pleasure and in no time they became my favourite shoes. They are remarkably comfortable, slipper-like in comfort when putting them on, and when quickly and easily adjusted they feel just great. The lack of weight is very apparent too, especially so when walking around.

On the bike, they are stiff at the sole as expected, but the malleable upper allows a little movement and my feet never felt restricted. If you are after the ultimate in a 'clamped in' fit these may not be to your liking.

In warm weather the under-toe vent along with that paper-thin outer skin is a blessing, keeping temperatures and sweating down a treat. I did wear them on occasions when I was caught out in wet weather and although they still felt light on the foot when wet – let's face it, there isn't much to soak any water up – the summer temperature was not cold enough to feel a chill. They certainly wouldn't work to your benefit in the colder months, although to be honest I'd be more concerned about ruining an expensive, classy looking pair of shoes – these would be kept for summer best.

There are a couple of niggles in amongst all this praise though. The biggest issue was the cleat fitment. Giro has used fixed mounting holes with no adjustability, and they're set further back towards the heel than any of my other shoes. This meant that although I could get the angle right owing to the actual cleat's adjustability, I couldn't quite get them as far forward under the ball of my foot as I would like. It hasn't caused any issues even after a few hundred miles, but it does feel odd for a short time as you transition between pairs of shoes.

The only other issue I encountered was that over time the laces have stretched a little, placing the Velcro portion further down the side of the shoe. It seems to have settled now but I'll be interested to see if it goes further.

Lastly, there's that price tag. These are Giro's flagship shoes and are some of the absolute lightest on the market, with the quality and selection of materials going some way to justifying the price. However, I recently reviewed the Lake CX-301s, which for the same size 46 weigh in at 201g per shoe and are over £100 less. At the extreme end, the 150g per shoe Rocket7s which are also lace enclosure-based, come in at a staggering £1,200, making the Prolight Techlaces cheap in relative terms.

Verdict

Some of the lightest shoes available with comfort to match, these should be high on your list if you can stomach the cost

road.cc test report

Make and model: Giro Prolight Techlace Cycling Shoes

Size tested: 46

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 says: "At 150 grams (size 42.5) these shoes completely change the game for any rider looking for the maximum advantage out of their gear. The Prolight Techlace™ is the ultimate expression of a pure performance shoe. The shoe balances ultralight construction with best in class pedaling performance using a stiff TeXtreme® Advanced Composite outsole and Techmesh™ constructed upper. When coupled with Giro's award winning Techlace™ closure system, you have the ultimate lightweight, performance and comfort cycling shoe."

They're superlight and comfortable summer shoes, but the cost is likely to be prohibitive for all but the most extreme weight savers.

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

Giro has used some of the latest technical materials to produce the Prolight Techlace, with the unusual (and in parts see-though) uppers made from Ultralight Techmesh™ with Teijin TPU skeletal overlay, the sole built from eXtreme Advanced Concepts composite carbon - the carbon fibre is woven in flat sheets instead of threads, producing a carbon fibre that's ultra-stiff, yet lighter because it requires less resin. The cleat mounting threads are titanium too, saving a little more weight and they won't rust either.

Also included is Giro's Ultralight SuperNatural Fit Kit, comprising a pair of Ultralight footbeds with adjustable arch supports (three different heights), made with X-Static® anti-microbial fibre.

Rate the product for quality of construction:
 
10/10

As you would expect for such a high-end shoe, the construction of the hi-tech materials is flawless and show no signs of premature wear.

Rate the product for performance:
 
10/10

If the shoes fit so to speak, they are star performers. The easily adjustable enclosures, ventilation and feather-like weight make for a great pair of shoes that you'll want to wear whenever you can.

Rate the product for durability:
 
7/10

These have seen a good few miles now, as if the weather was dry they were my default choice. I've been deliberately careful with them but you can't avoid the odd scuff or mark; just through pure wear the only thing I found that altered over time was that the laces do stretch a little, otherwise they are looking as good as the day they were unboxed.

Rate the product for fit:
 
9/10

For me they are probably the best fitting shoes I've tried; I have narrow feet and these shoes cater perfectly. On wider feet they might be a little restrictive, and although Giro does make wider fitting shoes in some models, this isn't one of them. Included with the shoes are Giro's adjustable footbeds that increase or decrease the arch support giving a good range of options over a standard flat insole.

Rate the product for sizing:
 
9/10

The size 46 tested here was spot on, with only a little extra length in the toe box over other 46s I've worn.

Rate the product for weight:
 
10/10

Weight (or lack of) is the biggest selling point for Giro here, and these tick that box with ease. These size 46s tip the scales at a scant 386g for the pair.

Rate the product for comfort:
 
10/10

Whether on a short local run or a century ride, the shoes were so comfortable you could forget you were wearing them at times. I use custom moulded footbeds with cycling shoes, but found that the adjustable insoles with the largest arch support were good enough to get through most rides without really noticing, only getting slightly uncomfortable on day-long outings.

Rate the product for value:
 
5/10

Yes, the materials used are high-tech and the construction is immaculate but you can't ignore that price tag. It does gall a bit that high-end shoes are getting lighter and more minimalist but the price rises.

How easy is the product to care for? How did it respond to being washed?

The man-made mesh constructed upper did get oil and dirt on it occasionally, but a damp cloth was all it took to wipe them clean again, with no faint marks left afterwards like leather materials can pick up. The laces however did soak up muddy water and grime and need to be carefully washed; no detrimental effect though.

Tell us how the product performed overall when used for its designed purpose

Road cycling shoes are designed to be comfortable and consistently transfer power to the pedals over any length of ride and these fit the bill on both counts. The easily adjustable techlace straps make changes on the move a doddle and the lack of weight made a difference, albeit a small one, to my rides. Comfort lasted all day long and the unusual uppers kept my feet cool for the duration, even in high 20s temperatures.

Tell us what you particularly liked about the product

The fit, low weight and comfort were big highlights and made them my go-to shoes.

Tell us what you particularly disliked about the product

My only gripe (other than cost) was the fixed position the cleat bolt holes. They are set further back than those on my other shoes and the lack of adjustability meant my cleats were nearer my mid-foot than the ball. It wasn't enough to create positional problems or foot pain, but it did feel odd until I had adjusted to it.

Did you enjoy using the product? Yes

Would you consider buying the product? Yes

Would you recommend the product to a friend? Yes

Use this box to explain your score

The materials used, construction, comfort and fit are superb, the only downside is that price tag.

There was a reason cycling shoes all switched from laces to velcro and buckles, oh, decades ago. Now, young people discover what older people already knew: shoelaces on cycling shoes suck.

Paying £350 for cycling shoes sucks!

Spending £350 on cycling shoes sucks.

Not having £350 to spend on cycling shoes sucks.

Spending £350 on cycling shows knowing that other people have no money to buy any shoes at all sucks even more.

Why do nice things cost so much?

Its a great score of 4.5 but i'm baffled why the reviewer has rated these on value as 5, yet even says in the write up that for the weight:price ratio they aren't really that far out.

Boa dials and cable are going to have much better longevity than material laces, a club mate only just had a dial break after 9 years, and still managed to get it replaced. I don't see giro offering to re-stitch new laces in to your shoes when they wear out.

Ah so this confirms something. I recently bought some Rapha shoes (made by Giro) in their sale and couldn't get the cleats far enough forward so sent them back. It sounds like this is a feaure of Giro shoes and my foot size. Never had this problem with my Shimano, Time or Sidi shoes.
