"And then there is this." Hmmm? The thing that caught my eye, is the date of Patent: 1990! I guess, there's still a few soles seeking improvement. I'll have to see if I can go to the Patent site and find out who, etc. Evidently there are 4 pages of explanation/description. Worth checking, I guess. That is, unless you, (Del), already know the answer. <G> Best Regards, Joe Garrett, RPT, (Oregon) Been There, Didn't Like It, So I'm Here To Stay! [G}
