CTM Ultra Carbon touches the ground with a full-contact rubber traction outsole. The energy return and take-off build through the Ultra Platform™, the tuned Ultra Carbon Plate™ and the hyper-springy popcorn-foamed Ultra Insole™. The high-caliber composition is then topped off with the one-piece fully engineered mesh Ultra Upper™. Five cutting-edge layers in unison for one Ultra experience.

Ultra Platform™

Ultra Platform™ is the ultra-lightweight foundation on which we build our Ultra series running shoes. The platform includes a perfect balance between stack height, drop and foot angle to enable runners to keep form as effortlessly as possible, which is essential when you want to run fast during a sustained period of time. Introducing an innovative carbon plate with precision split at front, Ultra Platform™ delivers energy return also during turns and on uneven ground. And featuring a traction outsole that works well on all types of surfaces, the platform offers the unique opportunity to conquer ultra trail marathons at high speed.

CTM Ultra Carbon REVIEWS

The CTM Ultra carbon was genuinely designed as an "any surface, any distrance" running shoes. It's heavy for a marathon running shoe but when compare to other trail & ultra races, it's pretty average.

Carbon-plated Propulsion

The stiffed plates enhanced the runner's pronation. As soon as you move forward, the stiffed platings lift the rear ends to encourage forward propulsion. Running uphill should be a breeze as it reduces the muscular stress on the legs on steep inclines.

Solid Platform on every Surface

The narrow sole and tall stack height is unstable on technical singletrack, but that’s to be expected since it’s not a true trail shoe. However, on gravel and pavement the Ultra Carbon is sturdy, responsive, and snappy

Ultralight Upper

The upper fabric is see-through and lightweight, and it’s almost entirely bonded instead of stitched. the mesh stretches to comfortably wrap over your midfoot and there’s plenty of room in the toe box for stable toe-off. The fit around the heel and ankle is narrow, and keeps your foot locked in place well, much like a racing shoe should, however the tall collar sat flush against my Achilles


  • Stiff and fast
  • Lightweight breathable upper
  • Grippy on gravel and dirt


  • Too unstable for technical trails
