X-BIONIC TERRASKIN X03 are extremely comfortable and well-cushioned trail running shoes designed for long training sessions, diverse terrains and first ultratrail tests. They combine the distinctive TerraSkin® control with additional cushioning, roomier fit and long-lasting comfort.
The patented SpeedFrame® construction enables vertical shock absorption while stabilizing the foot horizontally. A soft foam core ensures a comfortable landing, and the design maintains precise control on uneven terrain. For extra support around the heel and Achilles tendon, the 3D HeelCage system provides support.
The outsole SpinWeave® is designed after a spider’s web pattern. Adaptable studs respond to the ground shape and, according to the manufacturer, provide up to 27% more ground contact compared to competing models. The Vibram® MegaGrip rubber provides reliable grip on stones, forest trails, pavements, soil, and other varied surfaces.
The upper SkinKnit® conforms to the shape of the foot, ensuring good breathability and effective moisture management. The Skin-to-Trail connection system links the shoe with the included technical socks X-Socks. Matched ventilation zones improve airflow, and GripYarns fibers help limit foot movement inside the shoe.
The X03 model offers the most spacious fit in the TerraSkin family, providing more room in the forefoot and added comfort as feet swell during long runs. Maximum cushioning, a 6-mm drop and a stable platform enable a comfortable and controlled stride even after many hours of movement.
These unisex trail shoes are an excellent choice for beginners, recreational runners, and experienced athletes seeking comfort, stability, and reliable traction over long distances and mixed terrain.
The model generally fits true to size. X03 has the most spacious forefoot in the TerraSkin collection, providing more toe room and greater comfort on long distances.
