Also bring 2 pair of water socks and 2 pair of cheap sunglasses. Water Socks, Beware Water socks are great to protect your feet at the lake because they are made to get wet. They are highly recommended as standard equipment on the lake to prevent foot injuries, especially while riding PWC, then hiking. When your feet dry off they will crack, resulting is a painful situation when you get home. To prevent prune foot, always remove your water socks and go barefoot when it's safe, like on clean dry sandy beaches, on a ski boat or houseboat, etc.
Some people switch to thongs to let their feet dry off when on the docks, etc.
For those with naturally dry skin, take skin moisturizer along to use on your feet every night. Another trick is to use Vaseline on your feet every night and wear socks to bed to keep the Vaseline from rubbing off. A good solution for this is two square plastic pails of water, big enough for a size 12 shoe. Put one on the beach at the bottom of the houseboat gang plank ramp, full of water. Dip bare feet and stay barefoot or switch to thongs on the houseboat.
