Boot Sole Length Reference (BSL)

Below are the BSLs for each size of boot we carry.

Boots do not change shell sizes on the half size, only the liner. Pay attention to the sizing in each table. Scarpa and race boots break on the half size (25.5/26.0) while other brands/models break on the full size (25.0/25.5).

Note that even though the BSL may be the same between two boots, there can be differences in measurement between brands/models.

If you can't find your boot here Skimo.co might have you covered.
