Query: Rubber Overshoes for boots

The rubber boots were great, just one problem, they were too small. I had to return them & shipping costs were almost as expensive as the boots themselves. Had I bought them from a store I would have exchanged them for a larger pair (if available). That wasn't an option. That's the down side of buying online plus the time involved getting the merchandise.
