Query: Broken Boot! Not for serious skaters!!

I've been an avid skater for years and I went with K2 because my best pair of skates were K2s and lasted for SIX years before I had to replace them. I purchased the K2 EXOs for this reason.....now I admit that for the past 2.5 months I started skating for fairly long distances (20, 24 and 28 miles), I was training for a skate marathon. Within a week BOTH of my EXO skate boots broke! I'm furious because they won't cover the junction between the upper and lower boot! They have 2 bolts there that obviously will not hold up. I know how to tighten my skates, so a loose skate was not the issue...the plastic bolt that was not designed for serious skating is the problem. I'm buying another pair and I'll shell out the big bucks for these.....I'll never give K2 my money again though.If you're a serious skater, find another skate!!
