Just off to return the unworn pair of new boots once I've printed out the receipt. Lesson well and truly learned about ordering boots on-line without having tried them on first. The worn pair will do for shorter walks, probably mostly country walking, but not longer ones on pavements which most of my walking is. Still, means a nice long walk between the various boots selling shops. The skipping is proving fun... though not to be done before I've done some walking to warm up.
