I have 4 older LaCrosse boots ranging from non insulated 16" grange to ice kings. I bought a new pair of the 800 gram 18" insulated alpha burley sports and can tell you that they are a vast improvement over the older models. They are extremely comfortable and weigh about 1/3 less than my other pair of 800 gram insulated ankle fit burleys. Get them 1 size larger than your shoe size. If you have wide feet be careful because they tend to be somewhat narrow.
