This biker boot looks nice and sturdy, but is still super light and flexible. The profile sole is made of ultra-light phylon material. The upper is made of black croco-printed leather. The textile loop at the top of the shaft has a rubber patch sporting the Floris van Bommel branding. Thanks to the side zip running from top to bottom you don't have to undo the laces every time you put the boot on or take it off. The shoe is finished with premium leather lining.
