Time to upgrade from my "economy brands". I would like some experienced opinions on Alpinestar boots: I normally wear a size 10 shoe, do the Alpinestars run true to size and how do they compare to others? What about helmets? Is Shoei or Arai or something else the way to go? How do their sizes run? Anything else I should know when looking for these things? I am probably going to buy used unless there is some reason not to... Thanks in advance!!
