What do you mean? You wear boots or whatever you want to call them, not sneakers.

Waterproof boots or neoprene overshoes. I’ve also seen people with rain trousers that cover the shoes.

You can buy rain covers for your shoes, or just do whatever it is you do when you walk outside in the rain.

Ok good tip. Just to clarify. When I drive garage to garage, as many people do, I don't walk in the rain. When I do walk in the rain, I carry an umbrella, and that doesn't work on a bike
