Amazon カスタマー 5 This shoe cover is intended for short use and not intended as a "full time" use...just incase, if there are folks with an idea that it could be used as a "permanent" cover. The sole is rather "thick" which makes the show cover a little "heavier" that one would expect, but I suppose the thickness of the sole is necessary, to handle the "terrain" when in use. It is a good product and there is no "foul" smell typically associated if it was "cheap" plastic! A thumbs up to this product and am satisfied for its intended use.
