Georgia Boot assembled the upper of this men's Thermal-Tec 6 '' work shoe with dark brown full-grain leather; this 2.2mm thick material is exceedingly durable yet feels terrifically smooth. You'll be pleased with the padded collar's cushioning; not only is it comforting but it prevents these work shoes from digging into the back of your legs. The pull loop that has been positioned on the back allows you to remove the footwear with ease, while the lace-up design (the hardware is all solid brass milled - very durable) allows you to control the fit.
