Pack out is usually about a half size, so if you think your foot will still be snug and not move around after the liner packs out then you're probably good. When I used to fit people I would usually try to get their toes so that they were just barely skimming the front, not firm against the front or scrunched up, but just barely, barely touching because the liner will pack out. Every brand and model's toe box is different, so you will be able to wiggle your toes more or less depending on the brand and model and your foot shape (wide or slim), and you should be able to move them a little bit otherwise you will have circulation issues and be uncomfotable. If you kick the foot forward while the boot is on the ground and you feel your foot slide forward inside the boot, or if your heel lifts at all when you step then either the boot is too big or you need to tie them tighter. If your foot stays put and all the other criteria is met then you have a good fit. But remember to take my advice with a grain of salt because I am not there personally fitting your boots and you are the only one who really knows what's going on down in your boots and if it feels right. And I promise I'm not trying to make you second guess yourself. I'm just a huge fan of happy feet because your day really can depend on how your feet feel. Sorry for the long winded answer, but there is a lot more to boot fitting than most people think or take the time to consider
Thanks a lot for the detailed reply Arrrmaty! This actually really helped. I always though if the toes are just barely touching then it's loose. A lot of people say to have all of the toes touching the tip because of the pack out that will happen. The boots I have now have that barely skimming feeling but are more comfortable for me then having my toes all touching the tip (my toes would turn a bit red if that was to happen). When i kick with my boots on, they don't slide at all. Looks like I'll be keeping these boots!
