I am now able to wear these very cute sandals all day and feels like walking on clouds. I havent had any pulling or cuts from this one at all and it does a pretty good job. Also they seem slightly to small. 3-16-17 the fuzz on the back of the heals have rubbed smooth. Je suis vraiment satisfait de ce mondel. I am returning and am being charged shipping to do so. The slippers were perfect fit super comfy. That said, I did learn a lot from the book. It was very affordable and I think the quality is good for the price. I find that sport earbuds and tiny headphones are not enough of a visual deterrent, so I went looking for something large and bulky to visually signify that Im busy and do not want to be disturbed.
