I rig mine just like bandchaser does but on the big 4 we don't have a lot of stumps. Never had a problem with mine sinking much. If that doesn't work for you, take 3 pieces of noodle, put on 3 straps at front of sock. Use a wire tie to pull em down tight then wrap with tape as tight as you can pull it. That will for sure float them and if your socks don't have weights. Do same thing on the straps opposite the floats and wire tie or tie on with line some 1 oz weights to help it open easier.
