At the ride, Dave Rabe was ready to bet money that I'd lose those boots and to carry Gloves (which I always do).
Much to my surprise (and Dave's), whereas I did loose that first boot on the first day, the other boots all stayed put until I removed them after the ride. They'd been on a week.
The saving grace had to be the preparation of the hoof. As Christoph Schork says, it is the most crucial part, and it was. Cleaning and drying those feet thoroughly and keeping them clean before the gluing process can't be stressed enough. A few extra minutes of detail work saves the day. Vertical striations; sanding/brushing and some denatured alcohol sprayed on and toweled off. And the boots were happy to stay put, even if the glue mixture was probably a bit askew. My new mantra: prep the hoof..prep the hoof...prep the hoof.
