Just to connect this with skiing...
If you fit into any of the following boots (correctly), these cleats will fit you just fine...
-Salmon- Ghost, Falcon series, Gun, Foil, X-wave, and etc.
-Full Tilts- If your feet are hurting in your full tilts, they do not fit correctly
-Lange- Not sure on the models, but any of the upper models are usually fairly narrow
-Dalbello- Again, any high end model
I know this will probably mean nothing to NS, knowing that a huge majority of people do not have correctly fitted boots, but if by chance you do, the above models will fit fairly correctly last wise.
Cheers,
Ryan
