Alkali Hockey in Roller Hockey Equipment Posted August 16, 2017 · Report reply Guys, First off don't worry about the "Tron Guys" building the skates. Joe is still running Alkali and was always part of the development and creation of the original Alkali skates. He knows what he is doing. Also, he came to me for my opinions and thoughts on the skates, and I helped tweak the design, colors, fit, etc. As for the Nylon vs purlyn argument, the new skates that were launched have plenty of stiffness and durability from my experience.
