If your budget will allow, buy a pair of adjustable Force Fins. They are worth every penny and then some. BTW - you can find them for less $$$.

As far as footwear goes, I wear the Chota Kick Boot Bootie which happens to be on closeout. They are super comfortable.

Pumps are a crapshoot. I have a Bravo 6 which I've had for years that even has a pressure gauge built in and I love it. It's better than any pump I've tried.

Have fun and make sure to wear a PFD!
