KIPSUMMIT MAX trail view

BUILT FOR THE LONGEST DAYS

Ultra races expose every weakness in a shoe. Hours of climbing, demanding descents, swollen feet, and repeated footfall wear down runner and equipment alike. KIPSUMMIT MAX was built for that grind when quads turn to jelly on a rocky downhill or for the third climb when legs need help. It's engineered to hold its grip, its stability, and its structure from the first climb to the finish line.

ENGINEERED TO REDUCE COMPROMISE

Designing a max-cushion trail shoe is a balancing act. More cushioning often means more weight. More stack height can reduce stability. Softer foams can lose their responsiveness over long distances and take away ground feel. KIPSUMMIT MAX solves those tradeoffs through a combination of Fastech+, balanced geometry, and premium mountain components.

KIPSUMMIT MAX Features
  • 1. 360° Ultra-Comfort Fit: Generous padding across the collar, tongue, and upper wraps the foot to eliminate friction and accommodate natural swelling over long hours in the mountains.
  • 2. Integrated Lace Keeper: A discreet elastic band on the tongue to securely tuck away your laces, preventing them from catching on trail brush or vegetation.
  • 3. FASTECH+™ Dynamic Cushioning: High-performance foam delivering an ultra-plush landing and +21% energy return vs previous KIPSUMMIT to protect your legs over ultra-distances.
  • 4. Reinforced Rock Guard: A robust shield at the forefoot to effectively protect your toes from sharp debris, roots, and rocky impacts.
  • 5. Vibram® Megagrip Absolute Traction: Deep 4mm lugs engineered to guarantee maximum grip and exceptional stability across rocky trails, scree, and mountain mud.
Fastech+ foam technology

Fastech+: BUILT TO LAST


At the heart of KIPSUMMIT MAX is Fastech+, KIPRUN's proprietary foam platform.

Developed in-house through a Supercritical Fluid (SCF) process using 100% ATPU, Fastech+ is perfectly suited for long-distance mountain running.

It delivers +21% energy return vs. the previous KIPSUMMIT while holding its rebound over the full distance of an ultra. The rebound underfoot at hour 14 still feels like it did at the starting line.

PROTECTION FROM THE GROUND UP

A 360° padded upper wraps and holds the foot through the swelling that builds over hours on the move.

A 38.5 mm heel stack, 32.5 mm forefoot stack, and 6 mm drop create a stable platform built to absorb impact on rough, broken terrain and push the runner forward on runnable stretches.

Underfoot, the Vibram® Megagrip outsole with 4 mm lugs bites into rock, loose scree, and mountain mud, holding its line on steep climbs and controlling the slide on long, punishing descents.

KIPSUMMIT MAX Ultra Performance

DESIGNED FOR ULTRA PERFORMANCE

The farther you run, the more every detail matters.

KIPSUMMIT MAX was built to blunt the toll of accumulated fatigue — the lead-filled legs, the foot swell, the loose terrain that shifts underfoot.

It keeps its shape and grip as conditions change through the day, so the final miles move with the same control as the opening ones.

BUILT ON AN ULTRA MINDSET

KIPRUN athlete Mathieu Blanchard knows an ultra is never decided in the opening sections.

That philosophy guided the development of KIPSUMMIT MAX. Every engineering decision was made with one objective: helping runners cover more ground, hold their form longer, and keep moving when the race begins to take its toll.

Mathieu Blanchard: Kipsummit Max philosophy

“The first kilometers lie. The last ones tell the truth.”
