Adjustment Instructions Continued:
The table below gives approximate settings for a range of boot sole lengths.
Boot lengths falling between size breaks can be properly fit by moving just the heel end side plates one position forward
or backward. It may be necessary to adjust slightly to accommodate for size variances between boot manufacturers.
The Perfect Fit: Bail Tension.
With a proper boot to binding fit, you should be able to close the toe clip with one hand, and the lever should firmly contact the
boot. The toe clip set screw should be adjusted to lift the clip just enough to get your gloved finger under it. If you are unable to
get proper bail tension please contact us for additional instructions/suggestions as boot shapes vary with model and size.
