The same goes for your snowboard boots and bindings. These are integral parts of the interface that exists between you and your board. You may already spend hours lavishing attention on your board, but that doesn't mean a thing if your bindings and boots are in poor condition. Next to your snowboard, the most important pieces of equipment to keep in good working order are your bindings. A broken binding just won't perform.
Bindings can be either incredibly simple or incredibly complex, depending on the manufacturer.
To keep yours in tip-top shape, spend a few minutes inspecting the various parts for wear and tear. Do this every time you plan on spending a day riding. Carefully check for loose bolts and screws. Also check the binding straps for damage, especially if you have a racheting mechanism. Don't forget to check your base-plate bolts as well, because these can become stripped and loosen every time you change your stance width or angle, which many riders do several times a season.
