At 1,920g, the Endurance 88 is the heaviest ski in Group 1 — a reflection of its construction density rather than a lack of engineering intention. The VibeStop™ polymer embedded in six channels within the core is 50% lighter than the wood it replaces, which partially offsets the weight of two full Titanal sheets and a Maple core. The engineering distinction here is significant: VibeStop™ is a patented non-Newtonian polymer that exists nowhere else in ski construction, and its presence in the Endurance 88 represents a genuinely unique approach to vibration management.

The Endurance 88 earns the second-highest Arrow Efficiency score in Group 1. VibeStop™ technology adapts on demand — stiffening under high stress during aggressive turns and softening in lower-stress conditions — delivering a level of on-trail composure that two Titanal sheets alone cannot replicate. The 16m turn radius and 80% camber underfoot provide strong edge hold and carving precision on groomed terrain, while the 15% early rise and 5% tail rocker extend the ski's usability into variable and off-piste conditions. Renoun claims the Endurance 88 is over 3x more stable in rough conditions compared to skis without VibeStop™.
