This 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 supple black suede. At the top of the shaft a rubber patch sporting the Floris van Bommel branding has been attached. Thanks to the side zip running from top to bottom you don't have to undo the laces every time you put the boots on or take them off. The shoe is finished with premium leather lining.
