Nidecker bindings come in sizes Small, Medium, Large and X-Large (for adults).
We recommend to always physically check if your boots fit into our bindings, and that the straps fit well. For Supermatic bindings this is especially important to allow the boot to slide in & out easily.
Our binding to boot sizing-chart, found here for the Supermatic bindings and here for the rest of the binding range. You can also find this information on all our product pages and it is as accurate as we can get it.
Not all brands size their boots the same, and there can be differences in volume of the boots, so if possible please try to make sure that your boot works for that binding size, and try them in person if this is available to you.
If you are in the overlap zone and there's no way you can try them yourself, we recommend going with the bigger binding size to make sure getting in & out is as easy as possible. If you go with the smaller binding size, it might be tighter to get in & out, but you will also find more of a locked-in feel.
Between sizes Medium and Large there is a jump in strap-size (S/M versus L/XL straps), so that is also a factor to consider how much strap you want to cover your boots, as well as the change in ride-feel which comes from a smaller straps versus a bigger one.
Although we're compatible with all snowboard boots on the market, of course Nidecker boots give the best in & out experience with all Nidecker bindings.
