Savander Snowboard 146cm Head Bindings Northwave Opal Boots 22.5cm Thank you for viewing. I'm selling these because my child has outgrown them. Overall, everything is relatively clean and I think you can still use them for seasons to come. The Savander board seems to retail for over 50,000 yen, and the Northwave boots are also being sold for over 10,000 yen on Mercari. Northwave Opal [From the catalog] Experience fun with your crazy friends with Opal, a custom fit that is unmatched in high-end performance. It features a Hypershock sole and TF2 liner for the best fit and excellent support even during big landings. The 540 heel retention system is combined with the Super Lace closure to enhance heel and ankle stability, allowing for downhill riding with diamond-like precision control.
