RE: Changing footstrap settings for the day
I agree with you completely on this.
To the others who keep trying...
I agree with all the concerns.
Just because other manufacturers tried and failed doesn't mean it was a bad idea. They just didn't come up with sufficient technology.
I think it's a formidable task, because a solution probably does involve metal-on-metal threads, designed not to loosen, not to corrode, lightweight, and as steveC points out - double screws.
