Thanks for the review. I would worry that the exposed metal that attaches the eyelet to the sole would scratch on some surfaces. I envision scratching up hardwood floors with them. Also, how do they hold up to the abrasion of man-made surfaces such as concrete and blacktop? Do you think they will fair better or worse than I traditional knot?

Mr. Leigh,

The plug in countersunk into the tread and does not touch when walking on flat man made surfaces. It is intended for running on natural surfaces.

The longevity of the plug is not an issue.
