Realfoot winter shoes

Hi I wanted to ask if you have any experience with realfoot shoes, and I'd really love some feedback.

I have really wide feed and I currently have ahinsa shoes, which aren't that bad, but could be wider. I just found out about realfoot and I saw how wide their shoes are.

I wanna ask if any of you have some experience with those shoes and if you could probably recommend me something or tell me how they feel etc. Also because winter is approaching very fast, I'd love some amazing, warm, anti-slip and preferably all natural winter shoes. Would be great if they were waterproof as well. (However all natural shoes are usually very expensive and I don't wanna waste all my money just for a single pair of shoes, so I don't think I would mind if it was a bit synthetic.)

I've already found some on their site, however the sole looks quite slippery even though they say, it's anti-slip. So if any of you could help me I would be very happy.
