Looking to get a new pair of boots this season as I feel my current 1000 gram Grizzlies are doing their job anymore of keeping my feet warm. Last season I started fishing at night and plan to do more of it this year where it's colder. Any recommendations on a pair of boots that won't numb my toes in single digit temps? I'm also hoping that they're relatively light weight so I don't feel like I have rocks in there. I know what you may be thinking, and yes, I do want my cake and eat it too. Any advice/recommendations is greatly appreciated.
