So simple they work, simply thread the straps through the slots on your Spark Blaze or Burner splitboard bindings and tighten around boot collars to keep your game tight. Booster Straps provide additional support and responsiveness in tour mode, increasing efficiency and reducing fatigue.

Comments about Spark R&D Booster Straps - black:
I'd say the biggest advantage is when in touring mode and traversing on a hard-packed or icy slope. The straps add stability in the top of your boot allowing you to hold an edge better. Other that that it's a lot more strapping and unstrapping when in and out of ride mode.
