BravoverQuick Dry Barefoot Aqua Shoes - Mens Womens Beach & Pool Shoes for Swim, Surf & Diving

Do they fit to size or a bit smaller or larger ?

Can you wear them on normal roads as there's hole at the bottom can anything stab you through it or any insect go in from the bottom as there is hole

Do they have inner soles? If yes are they laid in loose, glued in, or sewn in?

Doesn't give a option for which size is needed. Thanks
