TevaMen's M Hurricane 4 Sandal, 0

My husband has a very narrow foot and usually wears a size 11, sandals are hard to find for him, would this be a good fit?

Is strap in the back adjustable ?

is it still mens-7 equals womens-9?

This hurricane 4 has longer toe straps than the xlt2? have a wide right foot that needs a long strap.
