When it becomes clear that our pint-sized shredder is graduating from their starter set, we grab the Atomic Hawx 4 Boot to open up more of the mountain to their wily ways. The Hawx 4 borrows from its big siblings with a polypropylene shell and four aluminum buckles to offer the same level of performance to little rippers. The progressive flex offers more support and stability so they can maneuver through tighter trails with greater control. They might not stand taller than our chest yet, but they'll be making the mountain look small before we know it.
