Made in-house by Spark R&D, the HARDBOOT DUAL HEIGHT WIRES are a pair of wedges that fit very easily on splitboards.
Offering two different heights, 55mm and 75mm, this pair of wedges allows for easy climbing with the right angles. It comes with a heel adapter that screws directly into the splitboard inserts, and places the double height shims exactly where they need to be, hitting the perfect spot on the heel of the hard shoe, no matter what size.
