I just received these today and am absolutely in love with them! I wasn't so into the chunky-heel type of look, but these looked so adorable in the picture that I may have converted to enjoying these type of shoes! Walking them around the house, they are so lightweight and not at all a drag to walk in. Very comfortable, though the material does seem to be quite cheap (especially with how light it is!). An earlier reviewer noticed how it seemed to be made of styrofoam and I see why she would think that, but the heel part is smooth and a bit harder than the styrofoam you see in some of shipping packages. However, if I put all the weight on the back of my heel and lift my toes in the air, it does seem to squish ever slightly under my weight (106 lbs) and doesn't have the best traction, but it's not to the point where I'd worry I'll lose my balance; it's still sturdy despite its minor flaw of quality. I will test this out on my vacation and am very happy with my purchase so far! I am normally a size 5.5 (U.S. women's) and getting the size 36 on here was perfect! + the ankle strap works out nicely to hold your shoe in place.
