So a few things to ask yourself. Are you going to be hiking/walking in them long distances. (i.e. weight and support) What is your primary usage environement. (hot, cold, wet, muddy, combination) Insulated? if so, what weight. Unless you are outdoors for long periods of time in wet/snowy conditions, you would probably just want a decent all weather boot. Summer and warmer weather boots should be lighter and better for breathing, Winter boots should be waterproof and have insulation. how much insulation depends on usage. you'll need less insulation if you will be walking in them allot as you will stay warmer but I have 1000g thinsulate in mine because Im hunting in them and may be sitting still for 5+ hrs in 0-15 degree temps. Tread - Get something that will be good for your usage. Whatever you end up with, get a set of Superfeet Orange Insoles. These things are awesome and by far the best insoles I have ever used. Recommended to me by multiple hunting guides including Alaskan hunting guides and climbers. I have a set of Irish Setter Grizzly Trackers with 1000g Thinsulate. Superfeet insoles. There are a few places in columbus that carry them. http://www.superfeet.com/
