After many years of research into materials and experimentation, CRISPI® has developed a system called A.B.S.S. (Ankle Bone Support System). A.B.S.S. revolutionizes the comfort and protection of the entire ankle area thanks to a combination of innovative materials that allow the footwear to contour gently your ankle. This system offers outstanding sprain protection even on the roughest terrain whilst supporting the ankle in all conditions, thus limiting fatigue on the lower joints even after very long walks. The A.B.S.S. is a huge step forward in the manufacturing and of footwear and CRISPI® dedicates this exclusive technology development to its customers.
