|: T-nuts can rip up the sole.
: The skateshopowner offered to make me some plates to put under my insole, shaped after the boot. What do you think? It sounds familiar to me. Does anybody have experience with that kind of setup?
Seems to be a nice guy. I'd go for it. As you can see from my howto, I used washers to protect the boot. Works reasonably well (well, it held up for 10 to 20 years, so I guess so). Some plates shaped after the boot should be even better.
