Well, live and learn. I see that kappa store..in the UK. Wonder if there are other kappa products out there. We've got cars/shoes..and what else? 
FEET and Sneeker shoes!!!
Carol and I have been to many National and several regional meets in the past including the first National Meet held here in Kansas City, Missouri on July 14th, 15th and 16th of 2006 before the Kappa's were even built, and I kept the sticker for that first Meet because being an emotional chap it was a fantastic Meet and then when we finally took delivery of Miss Red Eagle I attached the sticker from that first Meet on the inside windshield glass near the top.
Sometimes I just put the sneekers in the trunk and go with nude feet! Now, sorry about the slightly off topic post but most of you don't have size 15 B sneekers so there is a handicap indeed for driving long distances, but sometimes discard your driving shoes and just try nude, uh, feet, and see what happens, uh, to be honest there is a lot more feel with the flesh only!!!
You see, I have just one old pair of old sneeker shoes that I can drive "Miss Red Eagle" with and and yes, they are my driving shoes and by now they are getting a bit worn and smelly but they are good for long or short trips indeed! All you young chaps and gals who can drive with the Driving shoes are indeed lucky! I don't believe they are available in large sizes!
