To beef up your Mansfield Boots, we have partnered with Unsung Cobblers in Nashville, Tennessee for thick Vibram Sole program. These soles will be added to the bottom of your leather heels and soles, increasing the overall height by 1/2". This creates a winter-worthy tread that will carry you through the toughest of terrains, and slipperiest of sidewalks. Timing: 10 days
