try on as many boots as you can and get the one that fits your foot best.
your boots are the piece of gear that how they perform is entirely based on how they work for the individual rider.
the best feedback that you can get from other riders is going to be regarding the durability of the boot - fit is completely subjective and how a boot fits someone else has absolutely nothing to do with how it will perform for you.
that's about it. that is all you noobs need to know about boots. try lots of em on, and spend whatever you need to to get the right boot FOR YOU.
Fuckin Sticky Bitches.
Doesn't look like whining at all to me. It's a good point. I'm guessing a lot of people are going to try to buy online without trying them on first, especially coming into the sport new and not wanting to spend a lot. Beginners don't really understand why the boots are as important as they are and if we're going to give advice on gear in general on this forum, this most certainly should be stickied.
