Each Quad shoe is built on a last/cast of the customers foot. Other companies build the shoe off an impression of the sole, or a tracing. We build the whole shoe around YOUR foot. Options include heel height, toe raise, closure type, side carbon counter height and stiffness, color, and many other things. We will need to know what plate you will be mounting on the shoe, to build it to exact specifications. Not everyonw will need a full custom, that Is why we offer a stock shoe also!
