Sole Lenght/Last Width

In general people should not select a boot with a last width that is narrower than their foot. The closer the last width is to their measured foot width, the snugger and tighter the boot will feel (more performance but less comfort, less warmth). This means that people who have a medium width foot can either ski in a 98mm lasted boot or a 100mm lasted boot depending on what their performance vs comfort expectations are. In general, going too tight causes problems in regards to warmth and comfort, while going too wide causes problems of lack of control and potential discomfort due to the foot moving around inside the boot.

Ultimately, length and width are only two components of how a boot should fit. Other points to consider are for example instep height, heel hold, the fit around the calf, and general impressions of comfort and foot hold.
