Several times recently I’ve got caught in torrential rain on my way to and from work and had wet feet all day. What waterproof shoes or boots can I buy that are at least moderately smart? I need them to be smart enough to wear to work (semi- formal dress code people - do get away with eg DMs, suede shoes etc) and also to the theatre? Really impractical to wear wellies and change my shoes due to working in different locations. Large umbrella did bugger all for my shoes last time I got soaked
