Water Shoes

Water shoes are simply large, wickerwork basketlike devices which are worn over the feet (and come to mid-calf height). The thief balances in an upright position and propels himself across the water with a paddle or oar. The DM may insist on a move silently check at some stage. If anything happens to startle the thief (such as an arrow whizzing past his head or some monster rising up in the water), a Dexterity test may be called for to avoid falling over into the water.
