how much do they weigh?
I haven't weighed them but they are light. The sole is thick enough to withstand rocky beaches and sharp coral but not so heavy to "feel" heavy. They can also be used with SCUBA fins that require a light boot. They're great shoes and a plus for hikers who don't have waterproof boots or who encounter water with rocky bottoms that they would like to swim or bathe in. Highly recommended.
I don't know an exact wheight, but obviously they are very lightwheight
A few onces... They are light and fit nicely, but don't tighten the top lacing too tight
