Best is a VERY subjective term that’s dependent upon the person, the location, and the style/type of hunting. I’ve had PH’s that wore Merrell, Danner, Jim Green, Courtney, Chuck Taylor’s, Crocs and several other hiking or military style boots.
I’ve used Courtney, Merrell, Meindel, and Solomon hiking boot, as well as Nike’s. For me personally, I’ll likely take the Nike’s, Merrell, or Solomon’s on most every African hunt going forward, barring something I think I’ll be spending a lot of time in water. Gaiter wise, I’ve worn Kuiu and Courtney and will likely pick the Courtney’s everytime for Africa.
