This seems like you googled that and took the sponsored link as gospel. Every article I've seen mentions Crocs and tons of other brands over birks. I'm not even an advocate of Crocs, was just curious as I didn't believe the birks comment and have looked in to shoes a ton over the years. Birks and toe drop are a real thing and a pain

Kinda need to see the scaled down to icon version. As an image, I'd say the top one easily. As icon/logo, both seem too busy.
