D Rex ST Pro Hardboot Crampon

Built for the steeps, trusted by the bold. The D Rex ST Pro is our legendary hardboot crampon — precision-engineered for maximum bite, minimal weight, and total confidence when the skintrack turns sketchy.

Stay Sharp, Stay Confident
Crafted from 7075 aluminum, these crampons strike the perfect balance between strength and weight, with a low-profile design that cuts drag without cutting corners.

Smooth Touring, Solid Grip
The overmolded ST Axle delivers a friction-free touring experience that’s as durable as it is efficient. When the slope steepens, stackable riser blocks keep every tooth fully engaged, even when running heel risers.

Pack Smart, Move Fast
A nesting design saves valuable space in your pack, while quick-slide installation lets you lock in or release on the fly — no tools, no fuss.

Tech-Compatible Confidence
Optimized for Spark x ATK Tech Toes, and fully compatible with Dynafit Speed Radical, Speed Turn, and Low Tech toe pieces.

Lightweight. Durable. Proven.
The D Rex ST Pro is built for riders who demand precision on the climb and confidence when it counts.

Weight:  147g per crampon - Regular 

Compatibility, Setup, & Sizing

Climbing crampons for Arc & Surge (including ST and PRO versions), Magneto, AfterBurner, Burton Hitchhiker, and Nitro Vertical bindings.

Also compatible with Heel Lockers and Riser Kits.
