I've had LL Beaners since the 60's. The original chain tread is far outdated. 20 years ago I had My pair resoled to the bob that they were offering, much thicker sole. I still have these and they are very good for warm weather hunting. Use them every Spring & Fall. The last I knew, they would not do the bob any more in the regular Maine Hunting Shoe. For cold weather, I wear either a pair of Danners or Schnees.
