Why is my heel slipping?
What this may really mean
The rearfoot may not be locked in, or the shoe shape may not match your heel and instep profile.
What not to assume
Do not assume heel slip always means the shoe is too big; lacing and collar shape matter too.
What to check first
- Use a heel-lock (runner's loop) lacing pattern
- Check if the heel cup feels structured or loose
- Confirm your socks are not overly slick
What now
Test a heel-lock lace first. If slip remains after a short indoor walk, compare another size or last shape.
Boundary note
If slip causes pain, blisters, or instability, stop wearing the pair and get an in-person fit evaluation.
