I have tried all brands: Courtneys, Russell, Danner, Merrell, Vasque, etc. On my last trip to Cameroon, my ph had a pair of Lowa. He swore by them. I bought the Z6s in desert color and non gortex. They are the most comfortable boot I have ever wore. I have since bought same boot in gortex. I usually wear them every day except Sunday. Planning to purchase a 8 inch pair also.
