So to start out I got these boots 5 days before heading out to colorado to help a buddy on a sheep hunt.only thing I did for breaking in these boots was get on the treadmill and do a couple light runs .So fast forward to getting on the mountain and hammering out some really tough miles .I was absolutely blown away with how well these shoes handled the rocks and different terrain .To be honest I can't say enough great stuff about the shoe.Now They really aren't cold weather shoe that's for sure,but for early season you can't beat them .Would for sure recommend these for early season hunts or just trail hiking !
