Yeah, that's my big worry with glue-ons too. I've seen them fail when it gets really wet or really hot, the glue just doesn't hold up. Like, we had a stretch of heavy rain and three clients called about loose shoes within a week. It's not just the application, it's how the environment beats on them after. Makes me nervous for anything but a perfect, dry climate.

Yeah @janag24, it's wild what trips them up. Makes you realize airport security sees everything as a potential weapon first, a tool second. Like, my exacto knives for design work look just as bad on an x-ray. Traveling with anything niche means you're basically a puzzle for them to solve.
