I've been waiting for a trail shoe just like the Nike ACG Zegma Trail. Trail shoes are notoriously rigid, uncomfortable, and to be honest make you look like a dork! The Zega trail has all the stability and traction needed for technical trail terrain, but offers amazing cushion and response. I love running on trails and grass but in order to log miles I need a shoe that keeps me feeling comfortable from beginning to end. I wear the Zegma on trail/grass/dirt/gravel/road, and it performs on all surfaces. The two features I love most are the sole and the elastic mesh ankle cover. The sole has the perfect balance of beefed up tread and max cushion...without being overly bulky. I still feel fast running in these trail shoes, just like I would in a road running shoe. The elastic mesh upper is snug around the ankle providing an additional layer of support and keeps small rocks/debris from getting inside the shoe. But to top it all off, the shoe looks cool which is obviously rule #1. Bottom line, I love the ACG Zegma trail because it allows me to log lots of miles without my feet and ankles aching...all while looking good!
