The Men's Voyageur Mid Boot by KEEN is a rugged cruiser, but with its windows down for ventilation. Stripped of its waterproof barrier in favor of mesh lining, the Voyaguer Mid allows for more ventilation on hot summer days. The aggressive Outsole has 4mm lugs to bite into the terrain, providing excellent traction while the ESS shank provides torsional stability for a secure ride from valley to mountaintop.
