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.
