Try on boots and find the pair that fits your feet and your riding style the best. Whether they turn out to be cheap or expensive, it is what it is. It's not something you want to purposely skimp out on. I can generalize and say that brand new 2010 boots under $200 CAD full retail probably aren't very good, unless it's a softer park boot.
