Does heel-lock lacing prevent blisters?
It can reduce modest movement but cannot repair an oversized pocket.
Should tape be applied before hiking?
It can protect a known spot after fit and moisture causes are addressed.
Why only on climbs?
Climbing exposes vertical heel movement hidden on flat ground.
Can wet socks contribute?
Yes; damp skin can make existing movement more damaging.
Put the advice into practice
Use the full setup on stairs and an incline, stop after ten minutes and inspect for heat or redness before changing one cause.
Limits and cautions
Tape cannot justify continuing with repeatable heel pumping.
A boot that moves with the heel is the foundation; recurring lift requires a fit change.
