I am just back from 3 weeks hunting in Zimbabwe. I was crippled last year and 4 days before leaving France my hips and knees were so sick I wondered if I wouldn't send my son hunting at my place.
I have opted for very cushionned running shoes made by Salomon (Adidas).

Salomon trail pro 2

The result : I never suffered from tiredness or other ailments, I felt perfectly fit for a guy my age. I never regreted to use such low shoes even when climbing steep rocky hills. My opinion is that cushionned shoes help a lot protecting joints and the vertebreas, and they are light, so one can hunt all day long without feeling tired by heavy boots.
