For sup air, cheap rugby boots with short moulded studs. I find it better to avoid leather and get boots with synthetic uppers - means you can hose them down or wash them in a bucket at the end of the day and not worry about cracking leather.
I've found that wearing studs all day can cause a lot of foot pain, so I always replace the crappy insoles they supply with a set of these, which you can swap between shoes. Gives loads of arch support, just a shame they cost more than the boots themselves!
