Dr. Scholl's ShoesWomen's Classic Slide Sandal

do these have a good grip on slick floors?And are they noisy when you are on slick floors?

Does this version have the toe grip like the original used to have?

Hola donde puedo encontrarlas así pero con los pinchos en la planta de los pies ?

Is the buckle on these adjustable or is it for show only? I recently saw a pair that had a buckle but adjustment was done through Velcro.
