When I was hit by an idiot that pulled out ,(without looking, he admitted afterwards ) my ankle was trapped between my bike and his wheel arch as I was thrown over his bonnet. The paramedic that attended wanted yo cut my boot off but I wouldn't let him, so undid the zip and pulled it off though admittedly it was rather painful. My boots had a steel bar in the base, armour in the ankle and calf area, reinforced toe area so feet were fairly well protected. When the boot was of the entire area that covered my ankle collapsed over yo one side, as the armour had been destroyed. I suffered major soft tissue damage to my right ankle/foot,which meant two weeks off work and instructions to keep any weight off it,and it's still not perfect today and my accident was in the late 90's. Doctors told me if not for my boots I would have lost my foot
