The Calvin Klein® Biorgen boots are hiking-inspired lace-up boots refined for the city, built with a clean round toe silhouette and a padded tongue collar that secures your fit. A heavy lugged synthetic rubber outsole grounds the silhouette with traction, while the streamlined upper keeps the profile modern and sharp. They are finished with embossed Calvin Klein® branding at the lateral side. These ankle-high boots pair well with slim trousers or layered over straight-leg denim when the temperature drops.
