Calzuro has an aesthetic appeal that recalls the wood clog, but thanks to a very special anatomical insole on which rest small raised parts, designed to stimulate the sole of the foot - it pushes the blood that accumulates in this area upward.  It's an excellent aid for blood circulation in the legs for anyone working on their feet for many hours. These nubs have also been the subject of in-depth research in order to achieve an effective level of stimulating foot pump action (the second most important blood pump after the heart). Calzuro clogs have a real internal shape that physiologically adapts to the foot, retaining the internal arch and perfectly fitting the foot without slipping. In fact, Calzuro does not easily slip off even when running. Moreover, the height of the heel in relation to the floor has been specifically designed to maintain perfect posture for long periods therefore preventing back fatigue.
