Petrie is one of the few manufacturers where customization and individualization of personal preferences are actually carried out for 100%. CYB or Customize Your Boots is a program that has been developed for this very purpose. A conscious decision was made to go from a standard series of boots with regular sizes to an individual product. The perfectly fitting form and shoe size with the proper height and size of the boot's upper avoids the disappointment of any compromise. It should not be the case that someone has to choose a larger shoe size in order to get a specific width. It signifies a logical progression towards a specialized product for equestrian sports. It’s considered perfectly normal in athletics and winter sports that a shoe is fully adapted to the individual foot and leg. In equestrian sports, a sort of basic boot has been used for a very long time and for many decades no changes have taken place to that. Over the past 10 years significant changes are now being made in this area.
