So you're looking for a deep fitting skate with a moderately curved heel shape, like the Ultra G70, but with a regular heel width. Let us introduce you to the Supra 670. This new model features GRAF's MicroPoly Monocoque technology that achieves the perfect balance between form and function. The single shell construction integrates the frame into the quarter design for a lighter boot that flexes naturally with your foot for immediate responsiveness. Like all the skates in our 600 and 700 series you can expect premium features, including an AirNet lining and Thermolam construction, that have been tested and refined where it counts – on the ice.
