Hiking with the Keen Women's Voyageur Hiking Shoes on is like opening the windows and letting cool, fresh air into your stuffy apartment. Unlike many supportive hiking shoes that feel hot and stifling on summer days, the Voyageur Shoes' mesh linings provide breathability for your feet. The ESS shanks on these Keens provide torsional stability as you breeze down the trail, and aggressive 4mm lugs grip rough terrain.
