(re-post)
(I have made several of these over the years – cutting rubber wellington boots from knee height to calf and then ankle height.)
Waterproof. Comfortable. Easy on and off (no calf chafing; no bending and stooping; no heel wedging).
They carry the patina of a pleasant history.
They invite personalization. Fun to wear – on the street, in the garden, to an event. Threaded with rhinestones they could stroll the runways of Milan, London, Paris.
