The 100% shearling upper is the finest quality to ensure breathability and shape retention for many seasons. The footbed is the Haflinger cork footbed that you know and love, featuring many comfort features. The contoured heel seat helps provide shock absorption with each heel strike to help relieve pain in the back, neck, and knees. The rocker heel encourages the foot to "roll" forward to help you push off in a natural and balanced way with each step. The anatomically correct, cork and latex footbed gives your foot support but is soft enough to adapt to the unique shape of your foot, and the wool felt insole lining helps wick away moisture for year-round comfort. The thermal rubber outsole will accommodate endeavors in a variety of different temperatures since they are both non-skid and weather resistant.
