When Spark R&D teams up with ATK, you know it’s not just a collab, it’s a skin-track superweapon. The Spark R&D x ATK Tech Toes slash 20% off the weight of the originals, lock you in with ATK’s legendary Monolink tech, and make step-in feel smoother than butter on a hot pan. No adapters, no drama, just bomber retention, riveted pins that refuse to bail, and integrated crampon mounts so you’re ready when the track turns spicy. Built for hardboot splitboarders who want ultralight efficiency without sacrificing trust-your-life durability, these toes are out to perform.
Two Tech Toes
Integrated Crampon Mounts – Built-in claw mounts allow for easy use of the D Rex ST Pro Crampons.
Integrated Hole Pattern – For factory splitboards there is no need for an adapter. Slotted rear holes compensate for splitboard insert pattern compatibility and variability.

Robust Stainless Steel Screw
Aluminum Lock Lever
Weight – 5.22 oz / ea (148g) | 10.44oz / pair (296g)
ATK Monolink Technology – Ergal 7075 aluminum sidearms and monolink (single spring) technology. This design uses only one spring on one side of the toe piece to lock the boot in, which contributes to the overall weight savings.
Riveted Pins – Making the loss of a pin in the backcountry nearly impossible. Heat treated for wear resistance.
Center Screw – Robust stainless steel center screw for easy no tool installation
Lock Lever – Slimmed down aluminum lock lever saves weight and handles more abuse than plastic designs.
Can be paired with Spark Hardboot Dual Height Wires – Sold Separately
