ROH (Radius of Hollow) profiles can be used to create the traditional hollows most commonly used in hockey, including the most popular ½" and 5/8" hollows. Choose from 12 different radii—from the deepest hollow for extreme grip (5/16") to the shallowest hollow for unmatched glide (1-¼").

Looking for the grip you need with the added benefit of glide? The Flat-Bottom-Profile offer exactly what you are looking for – the best of both worlds. Available in four different thicknesses (3/8″, ½″, 5/8″, ¾″), the flat-bottom profile is a newly designed and optimized cavity with a flat bottom that offers improved glide while still maintaining the desired bite.

The hollow radius indicates how deep the groove is that is cut into the blade during sharpening. The deeper the groove, the more grip the blade has on the ice.
The flatter the cut, the more glide the blade has on the ice. A smaller radius (5/16”, 3/8”, 7/16”) cuts deeper into the blade and creates more bite, while a larger ring (1-1/8”, 1”, 7/8”) does not cut as deep and creates more glide.

Choosing the right radius is a matter of personal preference, depending on whether you want more bite or more glide. The most common hollow radius is ½". We recommend ½" for most youth players (lower body weight) and then increase the radius (5/8" or higher) as the player grows taller.

The right profiling, the right pitch, and the right center of gravity on your skates are crucial to taking your skating to the next level, giving you an advantage against your opponents.
We recommend re-profiling new blades and once per season.
