Motorcycle boots have a tough job to do.
They have to breathe away the rider's perspiration at all times, but prevent water coming the other way when that rider happens into a rainstorm. They have to be supple enough to conform to the riding position, tough enough to walk in. They must have scuff protection to stop the gearshift lever rubbing holes through the uppers. And perhaps most importantly, they have to provide abrasion and impact protection in the event of a crash. It's a tough job.
