Carnac vs Sidi sizing(15 posts)

Carnac vs Sidi sizingmaximum15

Currently have Carnac shoes, but they are just a little tight because I have wide feet. Thinking about trying the Sidi mega wide, but LBS doesn't carry any Sidi. Looking for information on length comparison between the two. If I wear a 44 in Carnac, would I still need a 44 in Sidi or something a little shorter or longer?

Don't know about the mega wides, but I had compared both the Carnacs and the Sidis (regular width) before settling on the Carnacs. I don't remember any appreciable differences in length between the two, but the Sidi's felt just the tiniest bit narrow on my feet, so I went with the Carnacs.
If you find the Carnacs to be tight (I find them very roomy compared to Sidi), then the mega wides had better be REALLY wide :) Any comments from others who have tried both?
Which Carnac?pmf1

The Legends are their wide shoes (44.5 Legend = 45 normal shoe). The other models are not as wide in the toe-box and run true to size.

I have never tried Sidi mega, but I'd bet they are not as wide as Carnac Legend. Their normal shoes are quite narrow (I spent a painful summer with a pair of Sidi G2 before I switched to Carnac Legend). I'd make sure you can try them, or return them if you buy the Sidi's.

Another shoe worth looking at is Time. They run kinda wide.
I have the Comets...dsc

I also tried the Ellipse's, and found them to to be about the same (width-wise), although of three different pairs I tried on (two different shops) the left shoe of each Ellipse pair seemed to have a seam or something running across my left small toe area, that really bugged me??? That's how I ended up with the Comets.
Try the Legends thenpmf1

Like I said, these are the wide toe-box shoe from Carnac. I have ridden them for years and been quite happy with them (I've got 2 pairs). i have a pair of their mtn bike shoes as well. They're not as wide, but I still find them comfortable.

Actually, the Legend, Ellipse and Quartz share the same last- the Comete and below are on a slightly narrower last.

As far as the Sidi MegaWide, they are wider than Carnacs- also try on a pair of Sidi shoes that are not Megas, but a 1/2 size of the size you ought to wear. The Sidi 1/2's are made on the same length last as the whole sizes, but have a more liberal use of material over the foot- effectively making them wider.
Interesting ...pmf1

That pair of G2's and my feet sure never got along. God, what miserable shoes. Never was fond of the dumb buckle either.

So all the Carnac shoes with the same sole (whatever its called) are the same size?

The Carnac shoes with the USC (is that right?) sole all share the same sizing. The ones with the universal sole also share the same (but different from the USC) sizing.

I noticed last night that bike catalogues selling Carnac shoes state that persons ordering the Carnac Legend should order 1/2 size smaller than they usually wear. They don't say that for their other shoes. Are they intentionally making the Legends a half size too big? I know there is a marginal trade-off between length and width in shoes. For my present dress-up job, my father bought me a pair of Allen Edmond shoes (I would never pay $270 for a shiny black pair of shoes with no cleat drillings). The guy there ended up recommending a shoe a half size smaller than I usually wear, but wider. They fit nicely.

I'm not sure why the catalogers say that- I will be the snob to admit that I have all three (Legend, Ellipse, and Quartz) in the same size. The Legend and Ellipse fit exactly the same, though the Quartz fits a tiny bit smaller due to the new insole design- if I put the Ellipse insole in the Quartz, it fits the same as the Ellipse. Don't ask why I have so many shoes...

Hey, don't be ashamed. I'm even worse with wheels.

I've got 2 pairs of Legends and one pair of Sciracco (whatever the mtn bike ones are). The second pair of Legends I found on sale at Performance for $99 a few years ago. I bought them and stuck them in my closet until the first pair began to wear out. Its nice to have extra shoes. They take more than a day to dry out if you get caught in the rain.

I just went through the process of comparing Carnacs (Legend and Ellipse) with Sidis (Genius 3 and 4). And although my feet are not particularly wide, I found that I was a 44 in both Carnacs and a 44.5 in the Sidis. FWIW, I ended up with the Sidi Genius 4 because I liked how the new two-sided adjustment on the top strap really helps keep my heel in place.

I wear a Carnac Lemond (like legend)43.5 and a Sidi energy 44.5 and my feet are slightly wider than the normal guy.

I'd order a larger Sidi than you think you need- they have a size chart at their site that is pretty accurrate- but it strikes me as non-standard- ie. their 45 is more like a US 10.5- regular shoes that are a US 12 are sometimes labled as a 45- so you get the idea. It is quite possible that a 44 Carnac would be a 45 Sidi, unless Carnac is equally as screwed up as Sidi when it comes to sizes. I'm guessing a Sidi "megawide" is a US "normal wide"- but I've never tried their wide- it just strikes me as odd that they would use such a bold term as "mega". I have a regular pair of energy and I love them- especially the fact that there is no velcro (I hate the stuff- it ruins any fabric it brushes up against), but it is a full size larger than any other cycling shoe I've owned, and they are still quite snug. I'd be very concerned about the return policy if you buy them online.

Here is how Sidi sizes their shoes;

Their length runs pretty true, a 44 is a 44 in most other shoes. Where the problem usually comes in is when people try to compensate for their width.

And on the width note, a normal Sidi shoe is based on a "D" width, that is standard, so they do not run narrow. They then have the Mega shoe which is based on a "EE" width. And they now have a narrow model which is based on a "B/C" width.
