For Istria on pebble beach I bought this cheap shoes. My expectations were not very high, even considering the low price. However, I was pleasantly surprised. The shoes, a number of purchases greater than usual, also attached to something fuller feet. They are made of a flexible mesh fabric that can be easily attract and the one fixed by a lace fit the foot. The sole is transparent rubber, sprayed and equipped with some profile, so that you have a good grip. The shoes have almost 14 days, without prejudice to the transitional water (approximately 30 m to some sharp-edged stone) almost unscathed. With our shoes, no sole sparked, at one point had a sharp edge cut. I found these shoes extremely useful, they would buy again at any time. A star deduction they receive, because the shoes in the water look buoyant, which I was a little annoying while swimming.
