I agreee with Jaiem. If you're fishing the surf, and don't want to walk on a mound of sand under your stockfoot within your boot, get the bootfoot wader. You will definitely get sand inside your boot from fishing in the surf which will rub on your wader stockingfoot and wear it out, if you choose to combine the stockingfoot with a wader boot. You also have to wear a sock under and over the wader for breathability as well as to protect the foot of the stockingfoot from sand abrasion. So, why not just go for the bootfoot which will keep the sand out entirely? I use the Orvis breathables and since they, as well as most bootfoot breathables, seem to have a leakage problem, I rely on their guarantee and return them if they get wet inside. Good luck!
