Spark Hardboot Dual Height Wires

Two climb angles, endless skin‑track comfort.
The Spark Hardboot Dual Height Wires bring a game‑changing addition to hardboot splitboarding. Crafted in‑house by Spark R&D, these heel wires offer two adjustable rise options—55 mm for a 12° angle and 75 mm for 18°—optimising stride comfort whether tip‑first or heel‑first on the skin track. The integrated heel adapter mounts cleanly into splitboard inserts, ensuring the wires always hit the perfect angle beneath your boot, regardless of size. Designed for quick field adjustments and lightweight performance, these wires are a must‑have for technical touring missions.
