Formerly known as Parabolic, Wilson's exclusive Edge Control Technology has revolutionized the Figure Skating World, allowing skaters of all levels to unlock their true potential. The unique state of the art design of an Edge Control blade allows skaters to center their weight in a way that is not possible with a conventional straight blade, dramatically improving stability for faster take-offs and more precise landings. An Edge Control blade tapers at the mid-section, centering your weight for a level of control and stability in edge-work simply not possible with a conventional parallel blade. The precision geometry of the blade remains unaltered so there is no lengthy adjustment period. You feel a new level of confidence the moment you step onto the ice. Taking care of your Edge Control blade is as easy as any conventional blade and requires no special sharpening techniques or maintenance regime. In fact, because Edge Control can be sharpened in fewer passes, your blades will hold their edge longer than any traditional blade. The only difference you'll feel when you upgrade to Edge Control is in your confidence and precision on the ice. Please allow 6 weeks for delivery.
