The special design of the islands facilitates breaking of surface liquid layers in places of work, while the suction side of the bead heels favor a direct grip on the bottom. All this translates into a high slip resistance factor. 
Rubber floor is suitable for different applications without affecting their physical properties. Poliuretanop midsole has been extensively studied to provide maximum comfort even in extreme conditions of use, creating an immersive feeling in the foot, increasing the surface of support. The most remarkable feature is its polyurethane plenty of support coupled with exceptional flexibility. It offers a higher absorption capacity at 30 Joules, more than 20 J. needed to meet the EN ISO 20345: 2011.
