A revolutionary lacing system ! Boot made of synthetic material with leather inside and urethane sole, using technologies previously found in modern athletic shoes and snowboard boots. Designed for protecting barefoot hooves in case of occasional riding or for orthopaedic treatment. Can also be used as a quix fix for the occasional last shoe. The Boa boot is easy to put on and take off due to a large opening and a revolutionary lacing system : just turn the knob to tighter the cable and adjust precisely the boot. The Boa offers an excellent traction on all types of ground without blocking the foot. It protects all portions of the hoof without joint interference during motion. Very good wear resistance.
