The Scarpa Ribelle Run Kalibra HT Women is a very robust and precise trail running shoe designed for short/medium distances and skyrunning. With its lug pattern, the running shoe offers maximum precision, grip, and stability on challenging and technical terrain. The Wrap360 lacing system, developed in collaboration with BOA®, allows for a complete wraparound fit. At the heart of this technology is the BOA® Fit System, which offers a precise, micro-adjustable fit in both directions and improves stability and control on technical terrain.
