Sperry's. Original Topsider with the extra arch support. I got probably 6 pair scattered around in different stages of decomposition. I like the white (ice) ones best, not the brown ones.
I also got some BITE sandals that are killer. Not the same ones that sydwayz showed. Mine have a nonslip instead of a knobby tread. They're great for jetskis, etc, or washing the boat and stuff. They have a toe gard and drain channels in them. I looked in the website that sydwayz showed and don't see mine. I got them from an editors recommendation blurb in Boating magazine - I agree, they are the shiznit.
