Although built to weather the cold, the original Astorflex Hiking Boot wasn’t intended for the harshest winter conditions. That’s why Astorflex created this upgraded version of the silhouette, which is anchored by a Vibram Arctic Grip sole for reliable traction on slick, icy terrain. The wool lining has been replaced with soft shearling for superior heat retention and wind resistance, making the boot ready for subzero temperatures. The upper features the same chrome-tanned suede—which feels broken in from the first wear—with a padded leather collar for a secure, locked-in fit.
