The Ribelle Run Kalibra G is the trail running shoe for mixed terrain and extreme conditions, when cold, snow and mud demand greater protection and enhanced reliability. Suitable for medium-distance training, in winter or in summer on softer, more technical mountain terrain. The key innovation of this shoe is the lace system, developed in collaboration with BOA®, that allows a complete wrapping of the foot.

Technical features

Features

• UPPER:The inner part of the upper, supporting the lacing system, is made of lightweight, breathable mesh reinforced with a microfiber structure and TPU film. The clean design features the iconic TPU band from the Ribelle family, which wraps around and protects the entire shoe.
• GAITER: KALIBRA GAITER designed to provide protection in the harshest winter conditions, Kalibra G features a Polartec® Power Shield® monolithic membrane. The water-resistant construction provides protection from snow, ice and moisture, typical of winter mountain environments. The Polartec® membrane gaiter, combined with the zip closure and Velcro ankle strap, further enhances water resistance while providing thermal insulation and breathability.
• LACING: The foot is fully wrapped without pressure points thanks to Wrap360, developed in collaboration with BOA®. At the core of this system is the BOA® Fit System with the Li2 dial, which provides precise, micro-adjustable fit in both directions, enhancing stability and control on technical terrain.
• SOLE: PRESA® TRN-04 is designed for highly technical routes where precision and grip are essential. Its 5 mm pointed lugs provide traction on mud and ice, while their layout creates self-cleaning channels. The SUPERGUM W compound ensures high performance on snow and icy terrain.
