When you're out hiking, it's inevitable that you'll come across patches of water. Maybe it's just a post-rain puddle, maybe it's a free-flowing stream that's standing in your way. With Nike ACG’s latest model – the Zoom Air AO – neither of these will be an issue. You see those little holes in the midsole? They're designed to expel excess water and keep you hiking, no matter the underfoot conditions you encounter. They're more than capable on dry land, too, thanks to concealed toggle laces – errand brambles won't be snagging here – comfortable Zoom Air cushioning and a lugged rubber outsole.
