Waterproof any pair of shoes by staying indoors
Waterproofing sprays cost money, wear off, and smell like a chemistry accident. There is a permanent, free alternative: remain inside.
Tested across three rainstorms. Shoes stayed completely dry every time. Works on suede, canvas, and even those mesh trainers that soak through if someone nearby mentions rain. The manufacturer of your shoes does not want you to know this.
