Fortunately the sizing was better explained on Amazon… If you decide to order the waterproof shoe covers that I previously told you about, there is one thing that you need to keep in mind. They need to be large enough to cover your shoes. Err on the side of caution, and order them larger rather than smaller. Mine are a size larger than my shoes, and they fit perfectly. Read the reviews as well, you should be able to get a good idea of what size to order from other people’s experiences.
