Modern Hikers with a Retro Heart In the late '80s, hiking boots stepped off the trail and became fashionable as well as functional. The Free Spirit combines a retro look inspired by that era with modern tech for a hiker you can pair with a daypack or your favorite pair of jeans. It features a dual-density midsole that's firmer around the edges for stability and softer in the middle for targeted traction. A GORE-TEX liner defends against deep puddles and sudden downpours. Triangle lugs on the outsole give you lots of surface contact for reliable grip on a variety of surfaces.
