Replying to What Are Good Boots?

Last december i bought a pair tecnica cochises and they were great for the first few weeks, but after that they started to not stay tight and create a lot of shinspace. Its gotten to the point where I can't even use the boots anymore because I have to undo and retighten every buckle and strap after any feature, no matter how small. I've tried every possible thing to make them fit and nothing has worked, so Ive decided to buy another pair because I still have a significant portion of the season left, as well as summer camp. I'm unsure of what boot to get and i REALLY want to avoid that same problem. I heard that they don't have to be specifically made for park as long as they fit right. Is this true? Some models I were looking at were the salomon xmax 100, the dalbello sports boss, dalbello kr rampage 2016, lange rx 120 2016. I don't want full tilts. I ski only park and I'm working on front flips, misty 5's, 720's, and semi advanced rail tricks if that helps. i have narrow shins. Any help would be greatly appreciated.
