Trask Bison Leather resoled with Vibram soles.<br><br>Mine have lasted 5+ years and are the most comfortable good looking shoes I have ever worn. Original soles were OK but I wore them out in about 18 months. Resoled by a local cobbler they cannot be equaled except by boots.<br><br>Not super high style for a suit but perfectly good for business casual and sport coat type attire.<br><br>Make sure you get the Bison Leather, it shows almost no wear, and looks very good after a wax.
