The boots that I bought last year are already set for the installation of studs from what I can tell (to include the colored round areas that indicate where I should place them.............I am such a loser). I will give the studs a try and start from there. Dean_MT has been more or less "My Guide"on this trip so far and if he doesn't see a need for me to purchase boots prior to the trip, then that's good enough for me.
The manufacturer's studs are a story by themselves in terms of price, I will take a look at your choice Fred and see what comes of it. I figure the only tough part will be finding screws without a point (just in case they are too long), but nothing a pair of 9 inch linemans pliers can't take care of.
