Never been worn. Changed my mind but too late to return. From the Vivobarefoot product page: “Zero compromise, total barefoot feeling. The Tracker Hi II FG are the best way to get out into the wild; stylish, warm hi top twist of our classic barefoot hiking boot. Forget stiff, heavy, clunky boots - these unleash the wild! This Vivo fits small. We recommend sizing up one size to allow for thick socks, espcially if you have a higher volume foot.”
