Fix your existing ones and buy the wife a pair in hot pink….she’ll change her POV within a week. It’s a win/win. You get to keep your crocs, keep your wife, and you look like a stellar husband for giving her the gift she didn’t know she needed.
Once my son’s size in crocs matched up to my wife’s size I will catch her throwing them on to take the trash out. Next thing you know she’s doing grocery pickup with them. Gotta play the long game and introduce them slow. Make it her idea.
