The Occlusion Effect: How Do You Walk with Earmuffs/Defenders?

[Elho]

I find that they thud because they're not tight enough to prevent that noise when I walk. Even with earplugs, I still hear the impact noise with each step. How do you avoid this? For me, they work well when sitting, but they're not great when I'm moving, or at least I worry that the thud might be making things worse. It's hard to tell.

Thanks very much for any tips.
