@WaterShoesNewbie Thanks for reaching out!
First off, love your username! Secondly, based on how you have described the shape of your foot, we think the Keen Newport H2 would be a great option. They have been making the Newport H2 for a long time (long enough, in fact, to have a retro version) and it has proven itself to be a top performing water shoe. They offer toe protection and really good grip with their siping feature on the soles.
Hopefully this helps!
