Kids Boots


Some kids are just born to be on skis. With Fischer Thermoshape boots even the smallest feet can get the perfect fit. Ski boots use the Mondopoint sizing system, so just reference our handy sizing table below to find the right size.


The right fit for kids

Time and effort spent on proper-fitting boots are well worth the investment. In the long run, you will not be happy buying boots that are too large for a child, hoping you can make them fit; or that a child will grow into a large boot in the future.

The inner boot will change over time, making a less-than-ideal fit become a bad fit. This also affects the insulative properties of the boot. If you have to crank the straps extremely tight for a secure feel, you create entirely new fit problems. The right fit is also absolutely essential to learn to ski properly.


Kids sizes

Fischer’s smallest size is 15.5 in the Mondopoint system. The RC4 10 Jr. Thermoshape is an example of an excellent boot for a child wearing that small size.

For larger kids the sizes start at 19.5 in the Mondopoint system. Boots such as the RC4 Jr. 20 Thermoshape become available at this size.

Fischer kids’ boots are designed with the needs of young skiers in mind. Their bodies have not fully grown or matured, so the fit and shape of the boots will not put undue stress on their anatomy. We call this design approach “Somatec”.


Four key points about kids’ boots

  • Children’s and junior boots will have a lower flex index than stiffer adult boots to minimize the strength needed to steer the skis and to maintain a proper stance. The Ranger 60 Jr. Thermoshape, for example, has a low, more forgiving flex index. For stronger, larger juniors, a boot like the RC4 70 Jr. Thermoshape has a much higher flex rating.
  • The cuff, or vertical ankle part of the boot, is relatively shorter than on an adult boot. This also makes the boot more manageable and comfortable for beginners. The smallest children will be more comfortable and better able to control their skis in a boot with a low cuff, like the RC4 10 Jr. Thermoshape.
  • The number of buckles affects fit and performance. A tighter boot means higher performance, but there must be a balance between performance and practicality. Our boots for the youngest kids have only one buckle to make it easier on parents and more comfortable for kids.The more advanced RC4 70 Jr. Thermoshape has more buckles for a more precise fit and enhanced control.
  • We design our kids’ boots so young skiers can easily learn to slip them on and off themselves. This lets them feel confident and adds to the overall family enjoyment of a day on the mountain.


Mondopoint System and sole length

In an effort to simplify and standardize sizes across all brands, the Mondopoint System is used for ski boot sizes. It is based simply on the length of the foot in centimeters from the big toe to the heel. Ski stores will always have a Mondopoint measuring device.

Sole length is not a factor in choosing boots or sizing, but it is a term you should be aware of. It is the measure of the outside bottom of the boot used to adjust the binding.

Our advice is to round upward as the better option if the child’s foot falls in between two sizes. And be sure they’re wearing their actual ski socks when trying on boots. Another tip is to try on boots later in the day, if possible, when the feet have slightly expanded.

Heat molded customization is the best way to ensure an optimal fit. Fischer partner ski specialists will be able to quickly and easily do this in-store. The RC4 60 Jr. Thermoshape, for example, has a moldable inner liner that will fit the foot like a second skin for increased comfort and control.

Finding the right boot and having it fit properly aren’t magic. But when you do it right, it’s magical.


Fischer children’s skis for a lifetime of fun

We know that if kids have positive early experiences with skiing it can lead to a hobby or sport for their entire lifetime. We believe high quality gear, even for the youngest beginners, is important for their safety and enjoyment.
