Great design , style, function, comfort and just sick. K2 is the only boot ill wear. I do put my own footbeds in (I have a really high in step or arch). The inner BOA is what makes this boot what it is. Having the inner BOA and outter lacing allows the rider to fully adjust the boot on their feet. I personally love that I can loosen and tighten my boot simply by releasing the BOA. if your looking for a great custom fit this is the boot for your shredding.
Well after 1 season on these and I have come to realize that they do not fit my requirements anymore. They more or less have fallen apart. I am an avid backcountry rider and i expect my gear to hold up to the rigors of playing in the deeps. I found that on long days the boots were saturated - dripping water off my socks. This was the case after skinning, sledding, and boot packing. If you are looking for a premium boot that is going to hold up to the back country dont buy these.
