How ist the „Boot“ correctly tightened?

Pull the strap together with plastic cover from the riveted end through the hole and then along above the heel to the next hole towards the buckle. Make sure the plastic cover extends on both sides of the holes by 2cm (7/8“ approx.). Then plastic cover can be cut to size.
Which of the two holes (upper or lower) is to be used?
In case where the rim of the hoof is lower than the lower hole – lower hole is used. – In case where rim of the hoof is higher than lower hole, - upper hole is used.

Following choice of correct hole tighten the strap – but allow one finger width of space between strap and heel.
It is suggested that the tightness is checked from time to time.
