This cycling boot is the most heat moldable boot on the market today. Bonts’ resin is developed in house and has been perfected over 35 years to be an extremely stiff resin that becomes pliable at relatively low temperatures. The base of the boot is moldable which means all stiff areas of the boot can be molded in a standard oven. You do not need to mold your boots if they fit you straight out of the box. To mold your boots, remove any cleats, laces or cleat mounting screws and innersole before molding. Failure to remove the innersole can result in it becoming deformed by the heat. Pre heat the oven to 70C/160F. Place the boot in the oven for 20 minutes. Higher temperatures will void your warranty and may damage your boot. Caution: Do not place your feet in the hot boots or you may burn your feet. Let them cool a little and test the boot temperature with your hand before placing your feet in the boots. Tighten the straps and allow to cool. If you have any lumps or bunions on your feet or if there are any areas causing discomfort, while the boot is hot you can use the round end of a screwdriver to press out any part of the boot. You can heat mold the boots as many times as you like.
