About Mondo Sizing

The first thing you probably notice is ski boots have a different sizing than shoe sizing. The ski industry calls it Mondo sizing. Mondo sizing is a standard boot size between all ski boot manufactures. Mondo sizing is the length measurement in centimeters of the INSIDE of the boot. It was developed to simplify the different sizes that are throughout the world. If you take a tape measure and measure the length of your foot in centimeters, you would get your Mondo size. One thing you should know, ski boot shells come only in full sizes. An example of this is a size 27.0 and 27.5 both share the same shell size and have the same inside length. Both are the larger 27.5. Sometimes only the inner liner changes.

Boot Fit

You’ve probably heard that “ski boots are the most important component of your gear.” While your boots should be comfortable, the proper size and flex keeps you in a balanced position which makes it easier to control your skis. Get the wrong size and wrong flex, and you’ll make it more difficult to control your skis. There are a few factors you need to consider before deciding which size and model to have;
  1. Your overall foot length.
  2. Your arch length.
  3. Your foot width.
  4. Your instep height.
  5. Overall shape of your foot.
  6. And your aggressiveness.

Were you aware most of us have one foot longer than the other? And did you know many times your arch length is different than your overall foot length. What about your width? Boots generally range in width from 98mm to 106mm. Do you know the width of your foot in mm? So which length and width measurement do you use? While many people take the easy way and choose a larger size, this is many times the wrong choice. A boot too big allows your foot to move around. I know what you’re thinking, “you’ll just tighten the buckles”. But that’s like buying pants too big. You can tighten the belt, but the rest of the pants still don’t fit properly! We all have our favorite jean brand that fits our body shape the best. Well you can get a great fitting ski boot by getting the right brand for your foot shape. Just ask your local boot fitter.

Ski Boot Model

Here’s a scenario! Your friend loves their boots. Best fit they’ve ever had and they’ve never skied better. What probably happened is your friend has a boot shape and stiffness that matches their performance and foot shape! Hence loves them. But that doesn’t mean that you should get that model. Your friend probably has a differently shaped foot than yours and you could require a different stiffness. We all have our favorite jean brand that fits our body shape the best. Well you can get a great fitting ski boot by getting the right brand and model for your foot shape. You can purchase a lot of things on-line, but if you’re considering purchasing ski boots on-line, you’re asking for problems. Like us, stores charge the same on-line as we do in store. So why take the chance and purchase on line when you can get the boot fitting service for the same price?

Ski Boot Flex

Just as important as fit, flex (or stiffness) is important. Without getting too technical, proper flex helps keep you balanced (forward and aft) on your skis. Too stiff of boot and you can't get forward making it difficult to initiate a turn or absorb shock and bumps. Too soft of flex and it’s difficult to relay the motion from your knees and legs which makes it difficult to turn and hold an edge. The boot industry doesn’t make things easy. They may have standardized sizing, but not flex. And ski boot flex ratings are not the same between manufactures. What that means is a 90 flex from one manufacture can be a different flex in a 90 flex from another manufacture. So how do you determine your flex? When trying boot on, make sure you can move your knees 4 – 5 inches forward at room temperature. If you can’t flex your knee 4 inches forward, get a softer boot. If you flex your knee consistently more than 5 inches, get a stiffer boot.

The Number 1 and Number 2 Ski Boot Problems

The number 1 ski boot problem is people usually purchase boots too big. The reason? People react to first impression when they try on boots. And usually the first impression is the boot is too small because the toes touch the end. But what really happens is the skier doesn't give the heel a chance to get into the heel pocket. So what do you do? Give the heel pocket time to develop. Put the boots on and loosely buckle them. Then stand and occasionally flex your knee forward. This helps slide your foot back into the heel pocket naturally. You should leave the boots on for 10 to 15 minutes. Keep in mind, if you stand straight up, (knees straight) your foot will slide out of the pocket and forward but this is not how you ski.

Problem number 2 is the wrong socks are used. Ski socks make a huge difference in comfort. Ski boots should always be worn and tried on with the proper ski socks for the best fit.
