At LCO we have found a new system that doesn't involve standard waders. The Wader Skins keep you warm in the chilling Pacific Ocean but affords you to roam wherever you please. 

The perfect combo for this system is Wader Skins, Simms Guard Socks, and Simms Flats Sneaker. 

For Fly Fishing the Surf, we prepare it to be a little on the loose side, whereas you are using it for surfing on the tighter side.
