Tapping the wall lets you hear hollow spots versus solid stud locations.

Have you looked into building a proper shielded box? I read that foil often fails against strong nearby WiFi sources. A real Faraday cage might be your only permanent solution.

Right? I used my old gardening knee pads for a shock job last month and it was a total game-changer. Could actually move the next day.

I totally get what patcoleman is saying about the setup time lol. So what was the tipping point for you on that job, like was there a specific change request that made you think "okay, I have to try the parametric thing or I'll be here all night"?

That "boom, no more slipping" moment is great, but it got me thinking. Heel lock lacing can hide if your boots are actually the wrong size. If the boot doesn't fit right in the first place, you might still get pressure points elsewhere. It's like putting a band-aid on a problem instead of fixing the cause. But hey, if it works and saves cash on new boots, more power to him. Just something to keep in mind before you rely on lacing tricks forever.
