The K2 Boundary has become one of the most popular boots on our wall. It's medium flex, custom fitting Intuition® liner, and Focus BOA® are what make this boot such a hit. The medium flex is ideal for the average rider looking for enough performance for your local mountain and still has enough juice for when you want to push it. With multi-layer density foam, the Control liner from Intuition® will mold beautifully to your foot as it breaks in. You can also have your local boot fitter heat-mold them to create the room and fit you need before ever stepping foot on snow. And don't worry if it's not perfect the first time, this liner can be molded more than once.
The one aspect about this boot that we love in any boot here at Berg's is upper and lower zonal lacing. The two dial H4/M3 Focus BOA® Fit System allows for you to adjust the upper cuff and the lower forefoot of the boot at different tensions. This is ideal for any rider who has a wider foot, but a skinnier ankle or calf. This is true for those who have an athletic calf, but a narrower foot. This kind of adjustment allows you to dial in the fit you want where you want without cutting off blood flow in the process. These are a few of the reasons why the K2 Boundary is often the first boot to sell out here at Berg's.

Fitting Your Boots
– To properly assess the fit of any boot you must lace or buckle it completely. The boot will feel small until you do this because your toes will be pushed to the front until laced or buckled. Also, keep in mind all boot liners stretch out and get bigger.
– First, lace or buckle the boot loosely. Next, flex into the boot to drive your heel into the heel pocket. Doing this makes room for your toes. Lastly, finish lacing or buckling the boot in a flexed position.
– Be sure to wear the boots for at least 10 minutes fully laced or buckled before making a determination. Remember these boots are not made for walking, keep your knees slightly bent and flexed forward into riding position. When doing this your heels should be pushed into the back of the boot and your toes should be comfortable.
– You should wear the thinnest sock you are comfortable with. Blood flow is the number one thing that keeps your feet warm. Adding more material around your feet with thicker socks increases the chances of reducing blood flow.
– To help your foot sit properly in your boot, you may consider an aftermarket footbed like Superfeet® or Sidas®. A footbed with arch support, not just cushion, helps align your foot in the shell and alleviates pressure points. Footbeds should be sized to your arch height and length, not your shoe size.
– Spend some time choosing your boots, they are the most important piece of your gear!
