These shoes are definitely water proof.
I normally wear a size 7. Bought size 8 shoes. They fit perfectly. The price of these shoes seems to wary widely from $37 to $50. So, look out for a bargain. I bought them for around $50. The price dropped to $37 within days of my purchase.
Am overall satisfied with my purchase. The only downside is that I find them very heavy. So, I feel weighed down when I walk in them.
