Boot recommendations

[ATbuckhunter]

Im going to get my father new boots for this coming season as his old boots arent in the best shape for hunting anymore. I'm looking for something that's leather and with high insulation (800 grams preferably). The reason I want leather is because we usually have to cross one or two very small creeks and id like a boot that's water resistant. I've heard some bad things about the rubber boot styles durability. Any one have any good suggestions? One last thing is id like to keep it with in $150 since my recent payment of my semester tuition hasn't left me with much money to play with.

Although not 800gram I'm a big fan of the llbean Maine hunting boot on 12in height. I put a set of their gore Tex liners on mine and my feet are warm until it dips below 25degrees or so. My last pair lasted me almost 30 years . My kids just got me a new pair this psst Christmas. They should last me until I get planted.
