My 800 gram Rocky boots were under $100 and they are doing pretty well. The key is to wait till the spring and get a good pair of boots on sale for an awesome price. Then use them during the spring, summer, and fall every once in a while to break them in. 800 grams seems about right for 10-60 degrees with a walking and sitting mixture. they aren't cumbersome at all to me. When sitting in colder temps, they can start to get cold, but It just takes a little foot movement to start warming them again. In warmer temps wile active they can get a little warm, but not too bad. I think 800 grams is a good balance. I do like my pack boots for 10 to -20 degrees, but they aren't fun to walk far distances in cause they are (big, fat, and very soft)= warm.
