The Z is made with a 3k plain weave carbon fiber composite base. The carbon is sourced exclusively from the world’s #1 carbon manufacturer, Toray in Japan. In the front, air vents pump air into the boot which are built into the TPU protective bumper. The Z skate starts out being built around a last that has been modified and improved for over 40 years by Mr. Inze Bont. The epoxy resin is the most heat moldable in the industry. Under the liner is a high quality memory foam that is 3mm thick and 50A in hardness so your energy doesn’t get absorbed by the boot.
