I'm a home inspector and wear these every day. I previously used disposables that ran about 50 cents/pair, needless to say these paid for themselves immediately, but the economy is just a side benefit. These are super durable, washable, waterproof for when your shoes are wet or muddy - red clay anyone? Just throw them in the washing machine. They look great in black and now I don't look stupid with white or blue disposables. Had my first pair for 9 months before I left them in a new construction house, someone else is likely wearing them now, Why not, they still looked new.  I've had several people ask me where I got them. I just bought more 2 pairs to have a backup. Made in the USA bonus! These are the shoe covers you have been looking for. Get 'em today.
