I absolutely love these shoes. I bought them prior to my weeklong trip to the Amalfi Coast in Italy and they were simply fantastic. SIMARI water shoes are made of breathable, quick-dry and elastic fabric and the pores of the material are small enough that very little sand gets in but even if it does you can remove the insole and rinse them easily. The sole is made of rubber materials and it is durable and provides an excellent grip. Great for hot sand, rough pebbles, or poolside. Available in dozens of styles and colors, at under $10 they are a must have for any water sport enthusiast.
