Mavic’s £900 Comete cycling shoes save 4.2 watts per pedal stroke

How much? Yes it's not a typo, Mavic's new cycling shoes really cost £900

“You could buy a car for that!” was the first response in the office when news reached us from Mavic for its brand new Comete shoes. They cost £900.

The new Comete shoes have been several years in development, the project began in 2011, with Dan Martin integral to the final phase of testing. That’s actually where we first spotted these news shoes, on the feet of the Irish cyclist at last year’s Tour de France.

What sets the Comete shoes apart from all other cycling shoes is a two-piece design inspired by ski boots. A one-piece carbon fibre outer shell keeps the weight low and stiffness high, with large vents and two rotary dials, while a removable padded bootie slips into the carbon shell. It can be removed for washing. 

- The best performance road cycling shoes

One of the advantages of the new Comete is a very low stack height (the distance between the pedal and shoe) and lower is generally perceived to be better, as it puts your foot closer to the pedal axle. Mavic has measured it at just 4.5mm. This, and a lower contour at the ankle, provides a claimed 19% increase in the available range of motion.

Stiffness was also one of the key objectives behind the new shoes, motivated by demands of professional cyclists it has sponsored over the years for a shoe with more rigidity for better power transfer without an increase in weight.

Of course, a £900 shoe isn’t going to come without some bold performance gains, and Mavic has some good ones. It says, and we’re quoting the press release here, that the Comete “reduces up to 15% the energy cost of the major calf muscles recruited during the pedal stroke” and that this translates to a 4.2 watt saving per pedal stroke. Obviously I need to get me some of these shoes because that’s a pretty serious marginal gain.

Yes, we're scratching our heads at the claim of 4.2 watts saved per pedal stroke, so we've contacted Mavic for confirmation. 

There’s a small catch. Mavic admits that the performance gains come at the expense of comfort. It’s also not possible to fit 100% of existing foot shapes, and it’s offering just six sizes from 40 to 47.5. The size is adjusted via the insole.

The Comete shoes aren’t going to be hitting the shops until 15th April and availability will be limited. At £900 we can’t see demand outstripping supply but we’re really interested to see what they’re like and how they compared to regular high-end shoes from the likes of Sidi, Bont, Lake, Shimano et all.

Yes they’re jolly expensive, you could get these John Lobb black leather shoes for £840 and save yourself a few quid, but they’d be rubbish on the race bike. 

So what do you think? Will you be saving up for them?

Do they come as a four bolt version for my speedplay pedals?  Because if not then I don't think I will bother with them.

April 1st is next week. you can't save 4.2 watts per pedal stroke.

you might save 4.2 joules per pedal stroke. which would equate to 4.4.2 watts at a cadence of 60rpm

Aah, but is it true to say, "At a stroke I saved 4.2W."

I humbly submit that to anyone prepared to spend 800 euros on a pair of Ti printed jockey wheels these must seem to be a bargain.  Someone might even notice you wearing these.

 

For the avoidance of doubt I think that the prices of the jockey wheels and these are both mental. 

 

However, SWMBO also thinks that £100 for a nylon t-shirt is daft,  even one with a zip and pockets.  So if you dump half a dozen of those on the floor and add arm warmers that don't fit, bib shorts and tights, baselayers, jackets and all the other stuff, not to mention n+x bikes and lights and little saddlebags that aren't right  and this that and the other, the cost of that small mountain of stuff is bonkers compared to the cost of the shoes, noting also that the mountain might just be topped off with three or four pairs of shoes, a few pairs of overshoes and toe covers and a pair of cleats whose wear indicators fell off after two days (£20 not well spent).

Now if only I could tell what was good before I bought it, wouldn't that be nice.  I suspect that the shoes won't make the Xmas list.  THe jockey wheels definitely won't.

£900 for a pair of cf gel shoes and some thick socks. Bargain.

Well at least you get a pair of them... and maybe the inner sock would make a nice pair of slippers too.

They even admit themselves that they aren't as comfortable, fine for use on the track maybe, but riding a few hours is kind of an important part of road cycling no?

Also they claim a 19% increase in range of ankle movement, is this a good thing? surely there comes a point where just because you can move a certain amount doesn't mean it's a good idea. There's so many things that just don't make sense, and the price isn't even the worst thing.

I'm sure the staff of road.cc would be happy with a car costing £900, but not a bike. Ofcourse is you did buy a car for £900, you wouldn't be able to do much with it, until you paid the same amount again for insurance and VED (remember that VED is no longer transferable).

What does "4.2 Watt per stroke" actually mean? Watt is the unit for power, and it doesn't make any sense to calculate a power per stroke, it would have to energy per stroke.

I have no idea if this shoe does anything and I don't even own any normal cycling shoe, but as a physicist I was drawn to the headline, which confuses me greatly.

I confess to the same degree of bamboozlement, but ultimately concluded that:

(a) the author of the piece didn't understand what he was writing, and mangled the press release (which I haven't yet been able to find), 

or

(b) the Mavic marketing team didn't understand what they were saying when writing the press release. Or didn't care, because it sounds good, and fake news is a la mode. And the author didn't apply judgment. 

or

(c) It's actually a sarcastic headline, mocking the manufacturer's marketing drivel.

 

I'll go for (c), though others less technical might take it at face value.

"4.2W per pedal stroke, my cadence is 90, that's 180 strokes. 756W saving every minute, innit."

We've contacted Mavic for a bit more clarification about the watt saving. For transparency I've added the slide from the presentation to the article above, so you can see for yourself Mavic's claims

Fantastic, thanks. My inner pedant can't wait for their response  1

I'm hoping to learn something akin to Specialized's Win Tunnel 'savings over 40km' metrics; although these seem illogical, there's actually sensible reasoning behind that method.

Still £800 cheaper than a pair of Adam Hansen's carbon racing clogs, so quite the bargain I'd say.

Wow, some serious claims, am sure the new intern will look forward to testing these so that we get a review that can ratify the performance gains.
