# Boot size v shoe size

I'm curious about what the typical spread is between shoe size and boot size.  In terms of US shoe size, I typically wear a shoe size 10.5 or 11, but I was just fitted for the Lange RX 130 and I was put in a 26.5.  To be clear, I'm not asking if 26.5 is the right size boot for me - I trust my bootfitter and my feet, and I'm happy with the 26.5s - but it did make me wonder if that much of a differential is typical or atypical.  Thanks in advance.

In my experience I find that most often my customers end up in the size they measure and a 10.5 to 11 foot would normally be a 27.  BNut if the boot you've chosen is comfortable as a 26 go for it, almost certainly you'll be better off than most skiers as they'd normally end up in a 28.

I always thought a 10.5 to 11 worked out to a 28.5 to 29 in a straight conversion, but if it actually converts to a 27, then a 26/26.5 isn't as much of a variance as I thought.

The 'conversion' from Mondo to street shoe size: take the mondo size, say 28.5. Add the numbers to the left of the decimal, 2+8 in this scenario, 2+8=10. Add the .5 ('cause consumers know they need 1/2 sizes...) and you get a 10 1/2... but that's not what someone wearing a 10 1/2 street shoe should be wearing, it's what the average person will feel comfortable in the moment they slide their foot into the boot in a ski shop. This is why mondo sizing is good, most consumers don't know what the numbers represent, so we bootfitters can 'trick' them into buying a correct size. If they knew that the boot they were buying was TWO FULL SIZES TOO SMALL!!! they would never even put them on.

Ditto to the above comments and will add that the Lange RS/RX shells trend a bit long inside relative to other boots in their respective size and sole lengths.

Ok - that's consistent with what I thought about the conversion.  My original question was with respect to the typical variance between the conversion size and the proper size.  In my case, it's a 2-3 size difference, and I was wondering if that much of a variance is typical or atypical.  Based on your response, it sounds like you're saying that a 2 size difference is typical (if that's not what you're saying, please correct me).

2 sizes is about right.  some brands fir a bit longer/shorter, and some people like/want/need a tighter or looser fit

Don't get too caught up in this.  Remember your comment originally about trusting your fitter.  Do the shell fit and go with what it tells you.  Can't explain why the CONVERSION between Mondo and U.S. is off but it is.  For your own conversion if you like, go to a shop with both U.S. Brannock and Mondo and you'll see the industry has a problem with its math.

The conversion problem arises from the fact that We (human kind) are mentally hard wired to not have our toes touch the inside of our shoes and the boot manufacturers know this, so they stick a little label on the front of there boots that they think will sell the easiest, this has nothing to do with skiing, it's called good marketing, the same reason we get rashes of fad boots that are here today and gone tomorrow. marketing defined--- anything to out sell the other guys.

As Lou said "trust your fitter" "trust your shell size", forget the numbers on the boots, they are there to help some college kid sell boots.

Thanks.  I wasn't concerned about it -just curious as to whether or not it was typical, and if so, why.

Not sure I follow.  The fact that mfrs put the mondopoint size on the boots without any reference to the US size might well be because of the conversion problem, but it's not the cause of the conversion problem.  The conversion formula clearly seems to be flawed, which begs the question, why doesn't the industry fix the conversion formula?

also different people want/need boots to fit different.

grandma vs racer might have the same shape foot, but want different things out of the boot.

Have no idea why the industry doesn't fix the problem but it has been this way for a long time.  Even without the problem shell fit is necessary so it really doesn't change anything.  We measure in the store in Mondo and there are no issues.

Lou

Also, keep in mind that not only do skiers have to keep in mind length - which is only a guideline - ski bootfitters and manufacturers look at the volume of the foot, which can play a huge role in what size may or may not fit depending on the boot and the foot shape you are dealing with...and as mtnlion said, the ability level plays a big role too.
