Sale: $79.00 - Retail: $130.00 The new Lite Rail system makes adjustment even easier than before, with a lever in the toe and heel of the binding to slide and fit a wide range of boot sizes. The LR 4.5 is best suited for young skiers that do not need a high release value, and has a great feature of accommodating both Adult and Child thickness boot soles. What that means is a new binding will not be required when the size 22.5 boot is outgrown and the skier moves to a size 23.0 or above. This binding is a great option for helping gear last as long as possible, because the binding does not need a remount when the boot is outgrown- A 2 minute adjustment takes care of it!
