I tried sandals. Didn't like that there was no toe protection. Tried regular sneakers (Chuck Taylors), but they stayed too wet too long. Tried neoprene booties. Fine for in the boat, but sucked for walking. Tried light weight "swimmie shoes" but they had no support for walking on land. Tried toed sandals (similar to Keen H20) but didn't like that gravel and sticks seemed to find their way between my foot and the footbed. Finally I settled on LL Bean Summer Sneakers. Though now discontinued, thee Vacationland Sneakers in the post above are very similar. I've also seen similar shoes made by Saolmon (Techamphibian), Merrell (Waterpro), Columbia (Drainmaker), etc.
I think these are darn near perfect for paddling. They drain well, protect the feet, dry quickly and provide enough support for short portages, lunch on shore or walking on rocky river bottoms.
