Mad Rock designed the Frenzy EZ to provide a consistent feel. The molded sole extends from the toe to the back of your heel, so you know exactly what to expect no matter what part of your foot touches the rock. The Frenzy EZs three rip-and-stick straps eliminate pressure points and allow you dial in the fit of your shoe to a ridiculous degree. The dual Mad Rubber toe rand creates essential smear for edging and prolongs the life of the shoe. Mad Rock added a gusseted tongue, padded cuff, and padded lining for a fit that feels like a foot massage. EVA foam absorbs shock when you contact the wall during rappels, and an antimicrobial treatment helps keep your hooves from smelling like a barnyard after a day on the limestone.
